Abstract

This chapter gives an brief overview of A/D-conversion focusing on delta-sigma modulators. For a comprehensive analysis of delta-sigma converters the reader is referred to later mentioned references. The sampling and quantization of analog signals is briefly discussed. The main converter specification items are introduced. Next, the principle of oversampling and delta-sigma conversion is covered followed by some architectural aspects and implementation approaches. Pulse-width modulation will be introduced based on a delta-sigma modulator for low voltage applications. Finally, the impact on jitter for A/D-conversion is briefly discussed.
