Abstract
A high speed transimpedance amplifier includes an inverting unit, at least one gain module, and a feedback resistor. The inverting unit has an input terminal coupled to a photodiode for receiving an input voltage, and an output terminal for outputting a first voltage. The at least one gain module has an input terminal coupled to the output terminal of the inverting unit for receiving the first voltage, and an output terminal for outputting an output voltage. Each gain module includes a first gain inverting unit and a second gain inverting unit which are coupled to each other. The first gain inverting unit and the second gain inverting unit dominate bandwidth of the high speed transimpedance amplifier. The feedback resistor is coupled to the input terminal of the inverting unit and the output terminal of the at least one gain module for determining a transimpedance of the high speed transimpedance amplifier.
