Wide dynamic range transimpedance amplifier

摘要

An apparatus comprising an amplifier circuit and a control circuit. The amplifier circuit may be configured to generate an amplified signal in response to an input signal. The control circuit generally comprises a differential amplifier having (i) a first input coupled to said amplified signal and (ii) a second input coupled to a reference voltage. The control circuit may be configured to control a gain of the amplifier circuit by adjusting the input signal based on (i) a magnitude of the amplified signal and (ii) the reference voltage.
