Abstract

This paper presents the design and simulations results of a switched-capacitor discrete time Second order Sigma-Delta modulator used for a resolution of 14 bits Sigma-Delta analog to digital converter. The use of operational amplifier is necessary for low power consumption, it is designed to provide large bandwidth and moderate DC gain. With 0.35µm CMOS technology, the S? modulator achieves 86 dB dynamic range, and 85 dB signal to noise ratio (SNR) over an 80 KHz signal bandwidth with an oversampling ratio (OSR) of 88, while dissipating 9.8mW at ±1.5V supply voltage.
