Adaptive configuration to achieve low noise and low distortion in an analog system

An electronic system comprising:

• analog processing circuitry comprising a plurality of circuit elements, the analog processing circuitry configured to receive and process an input signal;
• distortion reduction circuitry coupled to the analog processing circuitry and arranged to provide distortion reduction to a first subset of the plurality of circuit elements at a first rate;
• noise reduction circuitry coupled to the analog processing circuitry and arranged to provide noise reduction to a second subset of the plurality of circuit elements at a second rate;
• a distortion control module configured to adaptively adjust the first rate of distortion reduction based on a comparison of an amplitude of the input signal to a first threshold;
• and
• a noise control module configured to adaptively adjust the second rate of noise reduction based on a comparison of the amplitude of the input signal to a second threshold.

A method for reducing distortion in a signal processed through analog circuitry, the method comprising:

• providing distortion reduction circuitry to reduce signal distortion generated by a plurality of analog circuit elements;
• setting a first distortion threshold for the plurality of analog circuit elements, the first distortion threshold approximating an amplitude of the signal below which distortion reduction generates unacceptable signal noise;
• adaptively configuring the distortion reduction circuitry based on a comparison of the amplitude of the signal and the first distortion threshold by adjusting a rate to apply distortion reduction to the signal;
• and
• processing the signal through the analog circuitry using the adaptively configured distortion reduction circuitry to reduce distortion in the signal.
