Abstract
A voltage multiplier for relatively high output current has its design output voltage stabilized and rendered independent of process spread, temperature, supply voltage and output current level, by a stabilization loop driving the switch that cyclically connects to ground a charge transfer capacitance of the functional voltage multiplier circuit. The feedback loop comprises an integrating stage, stabilized by creating a low-frequency zero in the transfer function for compensating one of two low-frequency poles of the transfer function of the whole circuit.
