A non-slewing opamp for oversampled converters

In this paper we present circuit design and simulation results for a non-slewing opamp. The non-slewing behavior of this op amp is particularly well suited for oversampled sigma-delta converters and can be exploited to reduce the bandwidth requirements for such converters. The technique presented is general and can be applied to most op amp topologies. To validate our technique design results for an example opamp are also included in the paper.
