Abstract:
A new compensation system for an audio input reduces noise by matching feedback ratios in the positive and negative paths. A variable resistance network allows for fine control of resistance trimming in one of the signal paths, which allows for compensation between tolerance of resistors that are external to an integrated circuit and those that are internal to the integrated circuit.

Claim (Index 15):
An audio preamplifier implemented on an integrated circuit and comprising:\n an operational amplifier having an inverting input and a non-inverting output; and a configurable compensation circuit including a first resistor, a second resistor, and a configurable resistor network, the first resistor and the configurable resistor network in electrical communication between an input of the audio preamplifier and the inverting input of the operational amplifier, the second resistor in electrical communication between the inverting input and the non-inverting output of the operational amplifier, and the configurable resistor network including a plurality of resistors and a plurality of switches, each switch of the plurality of switches coupled between a different pair of resistors of the plurality of resistors and the inverting input of the operational amplifier.
