High SFDR analog optical links at RF/mm-wave frequencies

High-speed opto-electronic transmitters and receivers (Direct detection, Coherent)

Silicon photonics integration with electronics (hybrid, monolithic)


Radio-frequency integrated circuits have made a profound impact on the lives of people around the world through the introduction of low-cost wireless communication and internet.

First introduced at International Solid-State Circuits Conference (ISSCC) 2009, the cascaded constructive-wave amplifier combines features of traveling-wave and cascaded amplifiers for millimeter-wave application. The proposed technique amplifiers forward traveling waves while attenuating backward traveling waves through a cascade of stages that share a single transmission line.

Wireline communication is a rapidly evolving part of the modern network infrastructure. High-speed data must be transmitted between chips using electrical or optical communication over wires to reach the lowest power requirements.

As demands on communication networks increase, the interface between the digital and analog world becomes severely constrained.  We are looking a broad range of circuit solutions to meet these challenges.
