Abstract

This paper discusses the influence of nonidealities on the continuous time multibit sigma delta modulators, such as clock jitter and RC-tolerance. Another aspect that is discussed in this paper is the power dissipation of the modulator with RZ- and NRZ-feedback realization. Calculation details and simulation results for a low-pass continuous time third order sigma delta modulator with an oversampling ratio of 32 are presented.
