1. A delta-sigma modulator comprising:
a complex loop filter coupled to recieve an incoming signal, wherein the incoming signal comprises in-phase and quadrature-phase
signals, the complex loop filter having a plurality of integration stages, the complex loop filter designed to have a signal
transfer function constrained to be below a maximum signal transfer function peak that can be incurred at a predetermined
maximum value of the incoming signal without causing instability the delta-sigma a modulator, and
a quantizer coupled to the complex loop filter to receive an output of the complex loop filter and to generate quantized output.
