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 34):
A coder-decoder comprising:\n an audio preamplifier configured to receive an audio input signal and generate a reduced-noise version of the audio input signal, the audio preamplifier including an operational amplifier 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 an inverting input of the operational amplifier, the second resistor in electrical communication between the inverting input and a 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; an analog to digital converter configured to receive the reduced-noise version of the audio input signal from the audio preamplifier and to convert the reduced noise version of the audio input signal to a digital audio signal; and a digital signal processor configured to process the digital audio signal to obtain an enhance signal and to output the enhanced signal as an output of the coder-decoder.
