Abstract
A method and an apparatus for converting an analog input signal into a digital output signal using a sigma-delta modulator architecture with a digital tracking filter. The digital tracking filter may have and order greater than one, and the signal and noise transfer functions of the sigma-delta modulator architecture are chosen to provide a sigma-delta modulator architecture with a high dynamic range even if a relatively low oversampling ratio is used.
