Abstract :
A low-cost transimpedance amplifier (TIA) suitable for optical wireless communications is presented. The shunt-feedback TIA is designed using a feedforward current amplifier (CA). The bandwidth of the CA-TIA exhibits low sensitivity to the TIA gain. The optical receiver front-end is validated by both simulation and measurement.
