“…Finally, the output buffer is a large bandwidth tunable analog equalizer based on a differential pair amplifier cell. This architecture has already been reported in [6]. This output buffer can provide a boost with variable peaking frequencies thanks to the differential pair degeneration made by a couple resistor-varactor.…”

This paper reports the design and measurement results of a 1-tap feed-forward based analog equalizer, mainly designed with differential pair amplifier cells composed of Indium Phosphide (InP) heterojunction bipolar transistors. This analog equalizer exhibits a maximal peaking frequency and amplitude of 50 GHz and 12 dB respectively. Large signal measurements demonstrated an equalization at 100 Gb/s of a 3m-long 1.85-mmconnector coaxial cable, which represents a lossy channel of 20 dB at 50 GHz. To the authors' knowledge, this is the first analog equalizer reported with an equalization capability demonstrated at 100 Gb/s.

We report a continuous-time analog equalizer based on a differential cascode amplifier cell. Realized with indium phosphide double heterojunction bipolar transistors reaching a fT/fmax couple of 370/340 GHz, this circuit exhibits a maximal peaking of 10.5 dB at 85 GHz. The tunability is made thanks to a varactor, which can tune the peaking frequency from 30 to 85 GHz. This analog equalizer also provide a bandwidth of more than 110 GHz whatever the varactor settings, which makes it suitable for very high speed applications.
