Voltage regulation using a delta-sigma modulator, device and method

Abstract

It is described a voltage regulator device (100), comprising: i) a power device (150), configured to receive an input signal (151) and to produce a corresponding output signal (152); ii) a comparator device (110), coupled via a feedback path (140) to the power device (150), and configured to receive the output signal (152) as a feedback signal (141), and to produce a compared feedback signal (112); and iii) a digital modulation device (120), arranged between the comparator device (110) and the power device (150), and configured to digitally modulate the compared feedback signal (112), and to provide the digitally modulated signal (121) to the power device (150), wherein the digital modulation device (120) comprises: iiia) a delta-sigma (122), iiib) a quantizer (124), and iiic) a feedforward path (128), configured to feedforward the compared feedback signal (112) beyond the delta-sigma (122).
