The study, design and measurement of a continuous time analogue equaliser based on a differential cascode amplifier cell, using indium phosphide double heterojunction bipolar transistors (DHBTs) reaching an f T / f max of 370/340 GHz are reported. A bandwidth of more than 110 GHz is achieved and a peaking of 18 dB at 95 GHz is reached. Simulations demonstrated an equalisation at 205 Gbit/s. This is believed to be the highest frequency peaking reported to date.
