Abstract
Oversampling /spl Sigma//spl Delta/ A/D and D/A converters based on switched current (SI) cells are an option that offers great advantages when manufactured with digital circuit processes. However, SI suffers from non-idealities that limit the performance of oversampling /spl Sigma//spl Delta/ modulators. This paper presents a conventional second order /spl Sigma//spl Delta/ modulator using the SI technique with a compensation scheme that reduces non-idealities of the integrators improving the performance of the modulator for audio applications.
