VHDL-AMS model of delta-sigma (????) modulator for A/D converter in mems interface circuit

摘要

In the paper, VHDL-AMS model of delta-sigma (ΔΣ) for MEMS A/D conversion circuits has been developed. The developed model allows to simulate the change of the impulses sequence at the output of the delta-sigma modulator depending on the input signal and also to conduct the analysis of the delta-sigma modulator at the block design level.
