Abstract

One embodiment describes a transimpedance amplifier (TIA) system. The system includes a transistor arranged between an input node and an output node to set an amplitude of an output voltage at the output node based on an amplitude of an input current signal provided at the input node. The system also includes a negative feedback transformer coupled to the transistor to provide a negative feedback gain with respect to the output voltage to substantially increase transconductance of the transistor.
