This article describes conventional A/D conversion, as well as its performance modeling. We then look at the technique of oversampling, which can be used to improve the resolution of classical A/D methods. We discuss how sigma - delta converters use the technique of noise shaping in addition to oversampling to allow high resolution conversion of relatively low bandwidth signals. We examine the use of sigma - delta converters to convert narrowband bandpass signals with high resolution. Several parallel sigma - delta converters, which offer the potential of extending high resolution conversion to signals with higher bandwidths, are also described.
