Voltage regulator incorporating configurable feedback and source follower outputs

摘要

A voltage regulator especially adaptable for use with field-programmable gate arrays (FPGAs). The voltage regulator includes a frequency compensated differential amplifier, a configurable feedback network for setting the gain of the voltage regulator, and a plurality of source follower devices for driving the feedback network and providing a regulated supply voltage. A bandgap generator may also be provided for generating a reference bias voltage that is independent of temperature.
