Abstract :
This paper studies the clock jitter error in multi-bit continuous-time Delta-Sigma modulators with non-return-to-zero (NRZ) feedback waveform. It proposes a few useful formulas for the design of a less jitter sensitive NTF. The analytic results and MATLAB simulations show that in the design of an NTF, there is a trade-off between the in-band quantization noise and the jitter induced noise of the modulator.
