Transimpedance amplifiers using three cascade variable inverter gain stages

A study of a transimpedance amplifier (TIA) using three cascade variable inverter gain stages is presented. It is shown that wide dynamical range (−38 dbm) and high bandwidth (500 Mhz) TIA can be achieved. This configuration is good for the optical transmission of OC-3.
