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
