Design and Realization of a Single Stage Sigma-Delta ADC With Low Oversampling Ratio
… fine DACs can be noise-shaped by using a digital requantization (REQ) algorithm. A second-order single-stage sigma-delta A/D converter with 8-bit two-step inner quantization is proposed in this dissertation, which employs the feed-forward branches to reduce the integrator output swing. The …

Dynamic Element Matching Techniques For Delta-Sigma ADCs With Large Internal Quantizers
<p>This thesis presents two methods that enable high internal quantizer resolution in delta-sigma analog-to-digital converters. Increasing the quantizer resolution in a delta-sigma modulator can increase SNR, improve stability and reduce integrator power consumption. However, each added bit of …
