Fast and accurate jitter simulation technique for continuous-time ΣΔ modulators
Résumé
A fast and accurate technique for modelling and simulation of clock jitter in continuous-time sigma-delta (SigmaDelta) modulators is introduced. In addition to its high speed compared to the traditional jitter simulation method, the proposed technique is still continuous-time based, which is more convenient than discrete-time based jitter modelling suggested in other publications. The mathematical principle of the proposed technique, as well as simulations results, are presented and compared to other simulation techniques.
