摘要: An analog-to-digital converter (ADC) that uses delta–sigma modulation technique is less restricting to analog circuit specification, consumes power, and achieves higher resolution. This chapter presents an oversampling, second-order, fully differential design for a sigma–delta ADC, which suited audio applications. The modulator architecture first designed using the behavioral simulator in MATLAB then TSMC 0.18 μm single-poly six-metal process. Using sampling frequency of 6.4 MHz, oversampling rate 128 input amplitude −3 dB full swing, signal-to-noise ratio (SNR) 92 achieved simulations 89 from simulations. equivalent 15-bit
