Abstract
A reference voltage sub-system that allows fast power up after spending extended periods in an ultra-low power standby mode. The reference voltage sub-system includes a reference voltage buffer, a reference voltage keeper, an active calibration facility for selectively adjusting the reference voltage keeper output to match the reference voltage buffer output, and a selection means for selecting between the reference voltage buffer output and the reference voltage keeper output.
