"Exploring Limits on Frequency and Bandwidth in Silicon Integrated Circuits"

James Buckwalter, Assistant Professor, ECE, University of California, San Diego

This talk will discuss millimeter-wave silicon integrated circuits for wireless and wireline communication applications. Emerging wireless applications have suggested arrays that require RF front-ends with new levels of system integration and functionality to communicate with both high power efficiency and spectral efficiency. These applications place severe demands on RFIC designers. Additionally, emerging wireline challenges are accompanied by a migration towards short-reach, high-speed optical communication using silicon photonics. The use of constructive wave amplification has demonstrated circuit bandwidth exceeding 100 GHz.

To this end, I will discuss the following topics:

  1. Bidirectional millimeter-wave front-ends
  2. Advances in millimeter-wave power amplifiers
  3. Low-power, 40 Gb/s circuits in 45 nm Silicon-on-Insulator (SOI) CMOS
  4. Fully-integrated optical transceivers in SOI CMOS
