Design of low-power and high slew-rate error amplifier for fast transient CMOS buck converters

Abstract

The voltage boosting control (VBC) is presented to achieve low-power and high slew-rate error amplifier for enhancing the load transient response of dc-dc converters. The VBC is employed to increase/decrease the gate voltages of the output-stage transistors of the error amplifier, leading to large current driving capability with simple circuitry during… (More)
