摘要： An optical receiver, a method of operating an optical receiver, a correction based transimpedance amplifier circuit, and a method of adjusting an output of a transimpedance amplifier. In one embodiment, the optical receiver comprises an optical-to-electrical converter, a transimpedance amplifier, and a correction circuit. The optical-to-electrical converter is provided for receiving an optical signal and converting the optical signal to an electrical signal. The transimpedance amplifier is provided for receiving the electrical signal from the converter and for generating from the electrical signal an amplified electrical signal. The amplified electrical signal has inter symbol interference resulting from a reduced bandwidth of the transimpedance amplifier. The correction circuit is provided for receiving the electrical signal from the amplifier and for generating, from the electrical signal, an output signal including corrections for the inter symbol interference in the amplified electrical signal effectively increasing a bandwidth of the optical receiver.

摘要： A differential amplifier stage and method for offset cancellation include an amplifier having an input and an output. An internal offset cancellation circuit has an input for receiving a control signal to control offset cancellation in the amplifier. The offset cancellation circuit is integrated with the amplifier but isolated from the input and the output of the amplifier, and, in accordance with its isolation, an impedance of the stage is unaffected by the offset cancellation circuit.
