Abstract :
Continuous-time Delta-Sigma modulators are able to operate at higher frequencies than their discrete-time counterparts. However, they suffer more severely from non-idealities such as clock jitter. A method for measuring this clock jitter has been proposed. Moreover, the effect of the non-ideality are explained and a continuous-time to discrete-time conversion method is presented in order to aid in the analysis of this effect. The SC-R feedback circuit has been presented here to help eliminate clock jitter noise.
