Tutorial 1: Systematic design of low-power Analog/RF CMOS circuits using the Inversion Coefficient

Speakers:  

  • Prof. Christian Enz, École polytechnique fédérale de Lausanne, Switzerland
  • Prof. Willy Sansen, Katholieke Universiteit Leuven, Belgium
  • Prof. Thierry Taris, University of Bordeaux, France  

Abstract: 

The emergence of the Internet of Things (IoT) poses stringent requirements on the energy consumption and has hence become the primary driver for low-power analog and RF circuit design. Implementation of increasingly complex functions under highly constrained power and area budgets, while circumventing the challenges posed by modern device technologies, makes analog and RF circuit design ever more challenging. Some guidance would therefore be invaluable for the designer to navigate the multi-variable design space. 

This tutorial presents low-power analog and RF design techniques that can be applied from device to circuit level. It starts with the presentation of the concept of inversion coefficient 𝐼𝐶 as an essential design parameter that spans the entire range of operating points from weak via moderate to strong inversion. Several figures-of-merit (FoM) including the Gm/Id, the Ft and their product Gm*Ft/Id, capturing the various trade-offs encountered in analog and RF circuit design are presented. The simplicity of the 𝐼𝐶-based models is emphasized and compared against measurements of 40- and 28-nm bulk CMOS processes and BSIM6 simulations.

The reduction of power consumption at a given frequency is achieved not only by proper biasing, but also by dedicated circuit techniques. This reduction in power consumption will become even more important as CMOS scales down to 5-nm. Of the circuit techniques to be examined, the cancellation of parasitic capacitances is the first. It is followed by the use of negative resistors for both higher gain and higher speed. Then, the cancellation of poles by zeros in multistage amplifiers and by use of feedforward is discussed. Finally, cancellation techniques for noise and distortion will follow.  

The challenge related to the design of RF CMOS building blocks concerns the technology, the circuit topology and the synthesis to address a set of specifications defined by the application. To address it a 3-step design methodology based on the Inversion Coefficient is proposed. Integrated in a design interface the methodology is exploited to develop RF Low Noise Amplifiers (LNA). Two applications are further considered: Wide Band Inductorless LNA for multi-mode/multi-standard Radio applications, and Ultra Low Power LNA dedicated to 2.4GHz Wireless Sensor Networks. Four LNA topologies designed in three technology nodes (130nm, 65nm and 28nm) are compared and discussed.

The tutorial is organized in 3 parts: 

  1. Transistor-level operating point optimization using the inversion coefficient and various FoMs
  2. Circuits level power optimization using cancelation techniques
  3. RF circuit design with the inversion coefficient: Application to LNA Implementation

Tutorial 2: Spread-spectrum techniques for mitigation of inband jammers in RF transceivers

Speaker: Prof. Ramesh Harjani, University of Minnesota, USA

Abstract:
Spread-spectrum techniques have traditionally been used in the digital basedband’s of RF transceivers to provide multiple access and/or improved jammer resilience. In this tutorial, we examine and present spread-spectrum techniques operated at RF to provide inband jammer resilience. Mixer-first N-path filters have shown significant success in rejecting out-of-band jammers before entering the active receiver signal path. In this talk we will focus on the use of mixer-first N-path filters that use spread-spectrum techniques to reject in-band jammers. We will explore both DSSS and FHSS spectrum techniques and consider how such techniques inherently provide 10*log(N) jammer rejection. We then consider specific implementations of both DSSS and FHSS spread-spectrum techniques. In particular, we discuss two DSSS implementations, one that provides 20dB of in-band jammer resistance and another that uses Walsh code encrypted N-path filters to provide nearly 40dB of self-interference rejection. Finally, we will focus on the use of N-path filters for ultra-fast hopping transceivers that provide processing gain and jammer rejection of in-band jammers.

Tutorial 3: An Efficient Solution to Simulate Mixed-Signal Circuits in C  

Speaker: Yves Leduc, PhD, Hdr, Associate member, Polytech Lab, University of Nice Sophia-Antipolis

Abstract:
High-level modeling is essential in the design of advanced mixed-signal circuits. The designer is searching not only for speed, but to comfort his understanding of complex systems and to extract the specifications of the sub-circuits he will eventually have to build.

Serious modeling is not for a dilettante. It needs a solid know-how in the field of the application and a solid expertise in the organization of the test. A good designer is not comfortable with black boxes sold by EDA companies. He expects to understand exactly what is inside the models, what is not, and how the numerical computations are handled. The designer wants to be the pilot, but does not want to loose his time in the picky details of software programming.

Our target is a software for the modeling and simulation of sampled-data digital and analog systems.

We have chosen to use ANSI-C as the programming language. It is a solid-standard; it is very fast and very versatile. We have built a netlist compiler producing on the fly optimized C software codes, which are compiled and executed immediately. It is therefore a compiler of simulators. The language (called NAPA) is designed to describe mixed-signal circuits in a naturally streamlined netlist. The compiler provides a maximum of help to the designer by removing a lot of superfluous declarations while maintaining a strict control about the validity of the description. The designer has a fully access to the documented and formatted C code produced by the NAPA compiler.

The first version of the NAPA compiler was built in 1989 to respond to a strong demand to speed-up significantly the design of the first commercial sigma-delta converters to beat competition.

The code produced by the compiler has many original features. NAPA was conceived to be easily extended and to be fully open to host the functions written by the users. For 30 years, NAPA was enhanced and never failed to respond and sometimes to precede the demand of the users. Many cells, cell generators and functions have been collected making the NAPA environment a repository of best solutions in terms of activation, analysis tools and subsystem cells.

We propose to share the expertise we have built during these years. We will explain the structure of the software and we will detail the key features that make such compiler of simulators a powerful and safe solution. We will show how a set of simple rules in the construction of this compiler guarantee the full extensibility. We will first run NAPA on simple examples to comfort the understanding of the compiling process. A few more elaborate examples on practical subsystems will be run. A full exercise on a sigma-delta converter will conclude the tutorial. The attendees will be encouraged to load the software and play with this example on their personal computers (running Windows 64 bits).  

Its is important to note that NAPA and its ancillary software modules are all freeware!  

Biography:
Yves LeducYves Leduc was born in Charleroi (Belgium) in 1951. He received his Phd in Electronic Engineering from the Catholic University of Louvain in Louvain-la-Neuve (Belgium) in 1979 and his HDR from Polytech Lab of University of Nice Sophia-Antipolis (France) in 2014. Yves joined Texas Instruments France in 1980, and was elected TI Fellow in 1998.

Yves has participated actively to the migration to analog CMOS and contributed to the first successes of TI in mixed signal. He started immediately to promote and develop original methods and software solutions for the design of mixed-signal systems.

In 1990, he was sent for 18 months to the central research labs of Dallas to share the know-how in Sigma-Delta converters. In 1993, Yves created the mixed-signal design team of TI France. The team made the first mixed signal IC companions to the digital signal processors and contributed to the success of TI in the wireless telecommunication business.

From 2001 to 2011, Yves was the head of a team in charge of advanced system technologies with the responsibility to identify and solve the difficulties that the designers will eventually meet in their works. He proposed the digital modulation of VCO which was the keystone of the 'Digital Radio Processors' of TI, and the 'Smart Reflex' concept combining DVFS and calibration in a novel design methodology of SOCs. During his career, Yves presented numerous conferences and tutorials in many TI locations worldwide and in national and international conferences. Yves was also teaching analog and mixed-signal design for the last 20 years at the University of Nice Sophia-Antipolis.

Tutorial 4: Amplifier Efficiency vs Linearity: what physics does and does not allow?

Speaker: Prof. Dr. Earl McCune, TU Delft

Abstract:
Communications on both wires and wireless has a century of history fighting the tradeoff between providing acceptable linearity for needed signal quality and the power drawn (and paid for) to get that performance. Recent improvements in understanding this trade-off are presented which show more clearly, what is not only possible to achieve, but also how to achieve it.

Biography:
Having more than 45 years of experience in RF/wireless design and technology development, I have seen a lot of what does work – and what does not. More importantly, I understand how cost relates with communications performance. With the experience of co-founding two start-up companies – both of which succeeded to liquidity events – my ability to contribute extends well beyond technical issues, including: intellectual property portfolio development, product business startup strategies and all aspects of project, technology development, operations, and company leadership. My independent RF laboratory is extensive and is regularly updated. Phase noise, jitter, and frequency synthesizer dynamics measurement are a particular specialty. In my efforts now to “give back” to the industry I have enjoyed working with for so long, I have written two reference books with Cambridge University Press, one on digital modulation (using physics, and not math, as the window onto this material), and the second on dynamic power supply transmitters (envelope tracking, direct polar, and hybrid combinations). I also teach short courses on several topics.

Tutorial 5: Things you always wanted to know about the bioelectricity of living cells and their marriage with electronics – but never dared to study

Speakers:

  • Prof. Dr. Joachim Wegener, Fraunhofer EMFT, Germany
  • Prof. Dr. Sven Ingebrandt, RWTH Aachen, Germany

Abstract:
Cells are the fundamental building blocks of life. From less than 1um to several 100um in size they all share the inherent capability of complete self-reproduction at very different rates ranging from several minutes to days. The mechanisms of reproduction are similar among the different cell types but not identical. Cells from unicellular organisms (bacteria, funghi) or assemble to tissues and organs in multicellular organisms like ourselves. In multicellular organisms, cells have evolved very efficient and complex mechanisms to communicate with each other and exchange information even across long distances. This intercellular communication is vital to the functionality of the organism. The cell interior is separated from the environment by a highly functional semipermeable membrane that controls the exchange of matter between intra- and extracellular space. This dielectric membrane is highly permeable to gasses like oxygen and carbon dioxide or small-uncharged molecules like water but hardly permeable to inorganic ions and macromolecules. For the latter, the cell integrates transport systems into the membrane by which it strictly controls the passage of these materials into the cell or out of the cell. The cell surface is also the site where cells present and enormous number of different, physical and biological changes. For the most part, these receptors are proteins that span the membrane. Once they get activated by their individual trigger, the signal is relayed into the cell, integrated and processed intracellularly to provide an orchestrated and balanced cell response. Higher cells not only have a membrane to separate themselves from the extracellular environment, they also from an intracellular membrane system to form individual compartments inside the cell to allow different metabolic reactions to occur and to be regulated independently. Also these inner membranes are semipermeable and passage of ions and molecules is highly controlled.

Bioelectricity forms the basis for cell communication and is also key element of energy conversion in fundamental cell metabolism. The structural basis for bioelectricity is the inner and outer membrane system as it allows separating, accumulating and controlling the flux of charged chemical species. The physiological membrane of a living cell is a battery just as much as a biochemical transistor and an integrated circuit. This tutorial will introduce the cell with respect to its active and passive electrical properties. It will address how electricity and electric circuitry is used by mother nature to sustain life and to control cellular processes. Besides these fundamental aspects, we will address the physical tools and devices that are used to study the underlying principles, screen for ways to interfere with them (e.g. with drugs) and manipulate them for biomedical purposes.

Biography:
Joachim WegenerJoachim Wegener received his doctorate in 1998 from the University of Muenster and continued his scientific education as a postdoctoral fellow with Prof. Ivar Giaever (Nobel Laureate in Physics) at Rensselaer Polytechnic Institute in Troy (NY). In 2004 he obtained his “Habilitation” at the University of Muenster, Germany. Since 2008 he is full professor for bioanalysis at the University of Regensburg (Germany). His research interests focus on interfacing animal cells with physical transducers (e.g. planar electrodes, piezoelectric devices, …) to monitor the cell response to chemical, biological or physical stimuli without using any labels. It is the paradigm of his research to replace classical concentration-analysis by effect-analysis on biological organisms.

Besides his affiliation with the University of Regensburg, he is head of the division ‘Cell-based Sensors’ of Fraunhofer EMFT.
