Abstract
A system and method of converting an analog input signal to a linearized digital representation of the analog input signal. A measure of the analog input signal is compared to a threshold associated with a maximum dynamic range of a quantizer. A maximum amplitude of a random, analog dither signal is dynamically varied for perturbing quantization of the analog input signal in response to the comparison. The dynamically varied dither signal and the analog input signal are combined to obtain a dithered input signal. The quantizer converts the dithered input signal into the linearized digital representation of the analog input signal.
