Abstract
A transimpedance amplifier having a voltage amplifier and a feedback circuit coupled to an input terminal and an output terminal of the voltage amplifier. The feedback circuit includes an impedance element in parallel with a feedback resistive network. The feedback resistive network has a fixed effective resistance value. The feedback resistive network may have a first resistive element disposed between the input terminal of the voltage amplifier and a node, a second resistive element disposed between the output terminal of the voltage amplifier and the node, and a third resistive element disposed between the node and a ground terminal. Various systems utilizing a transimpedance amplifier consistent with the invention, including an optical communication system are also provided.
