Design and Implenentation of a Bandpass Delta-sigma Modulator Using High-Q N-path Filter, M.Sc. Thesis Sharif University of Technology ; Atarodi,Mojtaba (Supervisor) ; Sharifkhani, Mohammad (Co-Supervisor)
Abstract
Delta-Sigma Analog-to-Digital converters have been positioned themselves as robust reliable converters so far. The magic Of extracting high resolutions from low bit ADC has made them popular between designers. Previously, the noise-shaping magic was used in high-resolution applications such as high-quality audio signal converters. However, as the technology scales and proceeds, these converters are approaching RF applications, too. Power and OSR trade-off limits this progress. To increase OSR in bandpass delta-sigma modulators, more power should be consumed to increase the quality factor of loop filters. In this thesis, a systematic approach has been utilized. An n-path filter is employed...
