ABSTRACT:
A voltage regulator for a charge pump is provided with two input paths from a reference input voltage to a comparator, each path having a node between a capacitor pair. The two paths are alternately initialized and used to control the charge pump which generates a reference output voltage, so that the reference output voltage tracks the reference input voltage at all times. Each path has its own capacitor divider and switching circuitry to alternately connect the nodes between the respective pairs of capacitors to the comparator, which compares the nodes to a second voltage reference. Since the circuit is alternately initialized, any alterations to the voltage introduced at the nodes between each of the two capacitor pairs, are corrected to the proper level within a short time.
