A 3.3mw 91 dB SNR sigma-delta modulator in 0.18um CMOS process

摘要：

This paper presents the design and simulation results of a sigma-delta modulator that serves audio application. Accurate system and circuit design of the ADC enable it to meet the SNR of 91dB and standards while consuming only 3.3inV. The modulator is implemented in sMIC 0.18/μm CMOS technology and operates with a 3.3V supply.
