Abstract :
We report the design, simulations and measurements of two tunable analog equalizers. These circuits have been realized using indium phosphide heterojunction bipolar transistors reaching fT/fmax of 370/340 GHz. These analog equalizers provide a bandwidth of more than 100 GHz, depending on the settings. A varactor is used to tune the frequency response to equalize various types of 100-GBaud communication system channels.
