ABSTRACT:
According to the invention, a regulated voltage pump is provided which uses a chain of diodes between each of which is attached one plate of a capacitor for which the other plate is driven by a clock signal. The regulated voltage pump of the present invention uses feedback from the output signal to determine how many capacitors to pump. A comparator compares a signal related to the pumped output signal to a reference voltage (which may be the power supply voltage) and controls how many intermediate pumping capacitors receive a switching clock signal. Thus a regulated pumped voltage is provided.
