ABSTRACT:
A continuous time delta-sigma modulator having a sampling frequency includes a distributed resonator having a length about equal to a reciprocal of an integer times a velocity of a signal in the distributed resonator divided by twice the sampling frequency of the continuous time delta-sigma modulator.
