Abstract :
The effect of certain fundamental nonidealities on the resolution of a continuous-time (CT) delta sigma modulator are examined in this paper. We start by talking about the equivalence between an ideal CT delta sigma modulator and its discrete-time (DT) counterpart, then consider the effect of quantizer/DAC propagation delay, clock jitter, and the recently-identified phenomenon of signal-dependent jitter on the ideal performance
