Title
A wide-range DC/DC converter with 2nd order digital compensation and direct battery connection in 40nm CMOS
Abstract
This paper presents a digital DC-DC converter with 2nd order compensation and direct battery connect capability in 40nm CMOS. A combination of circuit and process technology is used to achieve an input range up to 5.5V with peak efficiencies of 95%. It also outlines an approach to optimize a control loop based on a sigma-delta ADC and higher order digital filter, which is demonstrated on a prototype achieving step response times under load below 38μs/V.
