Abstract	Sigma delta modulators are nice solutions to achieve high resolution with relatively simple analog circuits,Sigma delta are based on the oversampling technique, If the sampling frequency is higher than the Nyquist limit only a fraction of the quantization noise power falls in the signal band,A digital filter which rejects the out-of-band noise is required to increase the effective number of bits, Modern technologies allow higher and higher frequency of operation either in digital and in analog sections + For signals with a relatively small band it is possible to trade speed with resolution,Oversampling ratio + OSR
