Abstract :
End to end simulation of sigma delta ADC is described here. The first order sigma delta modulator is designed to work with an input signal band of 24 KHz at an oversampling ratio of 64 with a sampling frequency of 3.07 MHz. The analog section of the ADC is simulated in MATLAB as well as in excel spread sheet. Likewise the design of digital section includes the design of an FIR digital/decimation filter whose simulation is also presented here.
