摘要:
An apparatus and method for a regulated voltage boost charge pump for an integrated circuit (IC) device. The charge pump generally includes a plurality of switching networks and a lift capacitor that are intermittently coupled to an output capacitor or to a regulating transistor, a differential error amplifier biasing a gate terminal of the transistor, and a controller configured to alternate states of switches in the switching networks in a pre-selected timing relationship with a clock signal of the IC device.
