Higher Order Digital Delta-Sigma Modulator with Small Fluctuation: Sliding Mode Operation Approach


A new design approach of a digital delta-sigma modulator with small output fluctuation is proposed. The digital delta-sigma modulators are used in the digital-analog converters, the fractional-N phase lock loop, etc. and its output fluctuation is one of the important performances although a higher order modulator often produces large fluctuations. In this… (More)
