Design and measurement of very high bitrate digital ICs fabricated in InP HBT technology

In this paper we present various design aspects of very high bitrate ICs and in particular electrical simulation and transistor modelling. Circuits are fabricated in a self-aligned InP DHBT technology. High speed selector design is used as an illustration. Circuit measurements show excellent operation at 80 Gb/s (measurement set-up limitation). Circuit operation as a 40 Gb/s NRZ to RZ converter was also characterised.
