In one embodiment, the present invention includes a delta-sigma modulator formed of a loop filter coupled to receive an incoming signal, and a quantizer coupled to the loop filter to receive an output of the loop filter and to generate a quantized output. The loop filter may have multiple integration stages and a transfer function constrained to maintain stability of the delta-sigma modulator regardless of an amplitude of the incoming signal. Methods directed to design of such a delta-sigma modulator are also described.
