Abstract
An embodiment of the invention is directed to a buffer circuit having a closed loop negative feedback amplifier that is coupled to continuously drive a node to a predetermined set voltage. A precharge circuit is coupled to selectively drive the node at a higher rate than the amplifier. The buffer circuit is particularly useful for reducing the recovery and settling time of the node voltage when the node is suddenly subjected to a large, capacitive load.
