ABSTRACT:
An amplifier system with feedback current cancellation comprises an amplifier with an input, an output, and at least one stage. A feedback network communicates with the input and output of the amplifier. A feedback current cancellation module that provides a first current at the input of the amplifier that substantially cancels a second current provided at the input of the amplifier by the feedback network.
