Abstract

See full text

Systems, methods and apparatuses for efficient control of a pass device driven into its triode region of operation are described. Output drive capability of an operational amplifier driving the pass device is boosted during a transition of the pass device from operating in a triode region to operating in a saturation region. An exemplary implementation of an LDO controlling pass devices for providing burst RF power to a power amplifier is described. An alternative configuration that boosts the driving capability of the operational amplifier using an asymmetrical mirroring circuit is also described.
