Abstract

Oversampled Analog-to-Digital conversion has been demonstrated to be an effective technique for high resolution analog-to-digital (A/D) conversion that is tolerant of process imperfections. The design of analog modulators for oversampled analog-to-digital converters can be divided into two main categories, the multistage or cascaded modulator (MASH) and the single loop modulators. This paper gives an overview of the oversampled Analog-to-Digital modulator architectures and their tradeoffs. The design and analysis of a stable N-th order single loop modulator and of multistage modulator topologies is covered. A comparative analysis of these two dominant architectures is also presented, followed by a brief look at the future directions of oversampled converters.
