Title: PSpice simulation of A/D Delta Sigma Modulator
Post by eepkhc on Jul 14^th, 2003, 7:41am

I have difficulty to simulate A/D delta Sigma Modulator because I don't know which Op-Amp model I should use...and the op-amp for above modulator seems to have 2 outputs (most of the op-amp has only 1 output). I managed to try the switched capacitor implementation of RC circuits with 2 non-overlapping clocks, successfully. Unfortunately when it comes to switched capacitor A/D delta sigma modulator, I am stucked.

Please anyone, if you are using PSpice OrCAD 9.1, give me some hints.....
