This paper presents the design and implementation of a high resolution voltage-controlled oscillator (VCO)-based ΣΔADC for digital DC-DC converters. The proposed ADC adopts a robust VCO and a sixth-order delta-sigma modulation to attenuate the phase noise and output ripples. The delta-sigma modulati...
