Abstract
A transimpedance amplifier system (TIA) for stabilizing high gain and high frequency signals while minimizing parasitic capacitance effects on the transimpedance amplifier system. The TIA includes an operational amplifier having a first input terminal, a second input terminal, and an output terminal. The TIA also includes a signal generating device operatively connected with the first input terminal of the operational amplifier. The TIA also includes a T-network feedback architecture operatively connected with the operational amplifier at the first input terminal of the operational amplifier and the output terminal of the operational amplifier. The T-network feedback architecture has a first impedance network and a second impedance network. The T-network feedback architecture is configured to suppress parasitic capacitance from the transimpedance amplifier system.
