Abstract
A circuit for providing a fast stabilization of the reference voltage level produced by a reference generation circuit includes a clamping circuit which clamps the refernece node at a voltage approximately equal to the voltage produced by the reference generation circuit when the reference voltage level is disabled. When the reference generation circuit is enabled, the reference node has to be pulled only slightly to reach the proper reference voltage, thereby increasing the speed of the device and the clamping circuit is turned off.
