Abstract: Disclosed is a differential transimpedance amplifier. The differential transimpedance amplifier includes a common gate amplifier configured to receive an electrical signal from an input node, and a common source amplifier configured to have a feedback resistor and receive the electrical signal form the input node, wherein an output signal of the common gate amplifier and an output signal of the common source amplifier form a differential signal pair.

Abstract: Disclosed is a transimpedance amplifier. The transimpedance amplifier includes an inverter configured to have a feedback resistor and amplify a signal provided to an input side, and a common gate amplifier configured to be connected to the inverter in cascade and amplify an output of the inverter, wherein the signal provided to the input side is fed forward to a gate of the common gate amplifier through a gate resistor.

Abstract: Disclosed is a differential transimpedance amplifier. The differential transimpedance amplifier includes a common gate amplifier configured to receive an electrical signal from an input node, and a common source amplifier configured to have a feedback resistor and receive the electrical signal form the input node. An output signal of the common gate amplifier and an output signal of the common source amplifier form a differential signal pair. The common gate amplifier and the common source amplifier each includes a load having a transformer which removes an effect of parasitic capacitance.
