Nanoscale MOSFET Modeling for the Design of Low‐Power Analog and RF Circuits

Speaker: Prof. Christian Enz
Affiliation: Swiss Federal Institute of Technology (EPFL)

Abstract:  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.

This talk presents low‐power analog and RF design techniques that can be applied from device to circuit level.

  • It starts with the inversion coefficient as an essential design parameter that spans the entire range of operating points from weak via moderate to strong inversion.
  • Several figures‐of‐merit are developed to capture the trade‐offs in analog and RF circuits.
  • Very simple FET models are obtained and compared against measurements of 40‐ and 28‐nm bulk CMOS processes and BSIM6 simulations. The model is valid to cryogenic temperatures.
  • A simple technique to extract the basic model parameters from measurements or simulation is described.

Biography:  Christian Enz, Ph.D., Swiss Federal Institute of Technology (EPFL), 1989. He is currently Professor at EPFL and Director of the Institute of Microengineering and head of the IC Lab. Until April 2013, he was VP at the Swiss Center for Electronics and Microtechnology (CSEM) in Neuchâtel, Switzerland where he was heading the Integrated and Wireless Systems Division.  Prior to joining CSEM, he was Principal Senior Engineer at Conexant (formerly Rockwell Semiconductor Systems), Newport Beach, California, where he was responsible for the modeling and characterization of MOS transistors for RF applications.

Together with E. Vittoz and F. Krummenacher, he is the developer of the EKV MOS transistor model. Prof. Enz is the author and co‐author one book and more than 250 scientific papers.
