Abstract
A circuit for rapidly charging a capacitor for a transition between operating states is provided. A controlled reference voltage is provided to reference the circuit. A comparator compares signals at the comparator inputs and provides an output dependent upon the comparator input signals. The output of the comparator enables or disables a controlled current charging circuit. The current charging circuit rapidly charges the capacitor when enabled.
