Submicron scaling InP/InGaAs single heterojunction bipolar transistor technology with fT > 400 GHz for >100 GHz applications
ABSTRACT We describe a high-speed triple metal InP SHBT technology in this paper. With respect to scaling, we have measured fT from 300 GHz to 450 GHz, and fMAX from 200 GHz to 380 GHz. The proposed technology also features triple metal interconnections, MIM capacitors and NiCr thin film resistors. A CML static frequency divider is designed and simulated from DC to 122 GHz toggling rate at a power consumption of 141 mW.
