Abstract:
One embodiment describes a transimpedance amplifier (TIA) system. The system includes an inverter TIA stage interconnecting an input node and an output node and configured to invert an input signal at the input node to provide a first inverted signal component at the output node. The system also includes a noise-canceling inverter stage arranged in parallel with the inverter stage and being configured to invert the input signal to provide a second inverted signal component and to invert noise from the input node. Thus, the first and second inverted signal components constructively combine at the output node and the noise is substantially mitigated at the output node.

Claim (Index 13):
An optical receiver system comprising a transimpedance amplifier (TIA) system, the TIA system comprising:\n a photodiode to receive an optical input signal and to generate an input current signal in response; an inverter TIA stage interconnecting an input node and an output node and to invert the input current signal at the input node to provide a first inverted voltage signal component at the output node; a feed-forward resistor arranged in parallel with the inverter stage and to transmit a first noise component from the input node to the output node; and a noise-canceling inverter stage arranged as a voltage-gain common-source amplifier with respect to the output node in parallel with the inverter stage, the noise-canceling inverter stage being to invert the input current signal and the first noise component from the input node to provide a second inverted voltage signal component and a second noise component at the output node, the first and second inverted voltage signal components constructively combining at the output node and the first and second noise component destructively combining at the output node to provide an output signal having an amplitude that is approximately equal to a sum of the first and second voltage signal components.
