Abstract :
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 91 dB and standards while consuming only 3.3 mW. The modulator is implemented in SMIC 0.18μm CMOS technology and operates with a 3.3 V supply.
