Abstract :
This paper presents a proposal for the design of error cancellation networks of multistage ΣΔ-frequency discriminators (ΣΔ-FD). Analysis and simulation, based on z-domain models in Matlab, address the effect of using a frequency divider in the 1st stage on the output noise of MASH ΣΔ-FDs and so proposing the suitable error cancellation network. At the end, we compare our work to previously done work.
