Sub 5 ps SiGe bipolar technology

Abstract

A SiGe bipolar technology for mixed digital and analog RF applications is presented. Balanced device performance is achieved with a transit frequency f/sub T/ of 155 GHz at a collector emitter breakdown voltage BV/sub CEO/ of 1.9 V, a maximum oscillation frequency f/sub max/ of 167 GHz, and 4.7 ps ring oscillator gate delay. With a 99 GHz dynamic frequency divider and a 19 GHz LNA with 2.2 dB noise figure state-of-the-art results for high-speed digital and analog applications are demonstrated.
