Abstract :
Design of continuous-time sigma-delta modulators with an arbitrary feedback waveform is discussed. The approach exploits the fact that the quantiser input is sampled only at discrete instants. Proper choice of the modulator coefficients allows for an exact mapping between discrete-time and continuous-time systems, regardless of the feedback waveform
