In this paper a new multi-loop delta-sigma modulator is presented. This multi-loop modulator is insensitive to low gain opamps while maintaining the stability advantage. As a proof of concept, a prototype was implemented to show the functionality of this structure. Measurement results shows that with open-loop opamp gain of only 35 dB, this prototype achieves over 74 dB SNDR at oversampling ratio of 16. The sampling frequency is 20 MHz and the total power dissipation is 3.2 mW from a 1.2 V power supply.
