Abstract
In this work, the modeling and design of a 10 bit first order delta-sigma analog-to-digital converter in 0.18 μm CMOS process for audio applications will be described. The peak signal-to-noise ratio (SNR) simulated using Matlab program for a 1 KHz sine wave is 78 dB which corresponds to a resolution of 12 bits. The design and analysis of delta-sigma adc was done in the Cadence® custom IC design tool. The transistor level implementation of delta-sigma ADC was done in Cadence.
