1. Caldwell, Trevor. Delta-Sigma Modulators with Low Oversampling Ratios.

Degree: 2010, University of Toronto

This dissertation explores methods of reducing the oversampling ratio (OSR) of both delta-sigma modulators and incremental data converters. The first reduced-OSR architecture is the high-order cascaded delta-sigma modulator. These delta-sigma modulators are shown to reduce the in-band noise sufficiently at OSRs as low as 3 while providing power savings. The second low OSR architecture is the high-order cascaded incremental data converter which possesses signal-to-quantization noise ratio (SQNR) advantages over equivalent delta-sigma modulators at low OSRs. The final architecture is the time-interleaved incremental data converter where two designs are identified as potential methods of increasing the throughput of low OSR incremental data converters. A prototype chip is designed in 0.18um CMOS technology which can operate in three modes by simply changing the resetting clock phases. It can operate as an 8-stage pipeline analog-to-digital (A/D) converter, an 8th-order cascaded delta-sigma modulator, and an 8th-order cascaded incremental data converter with an OSR of 3.
