摘要
A voltage regulator includes an amplifier having first and second outputs, a feedback path coupled between a first input and the first output of the amplifier, and a feed-forward path between the second output of the amplifier and a switch coupled to a reference potential. In operation, a first control signal from the second output of the amplifier is generated based on a comparison of a reference signal and a feedback signal into the first input of the amplifier. The first control signal controls the switch to maintain a substantially constant supply voltage. A second control signal is generated along the feedback path to control controls the amount of supply voltage.
