ABSTRACT:
A multiphase charge pump including first and second phase charge pump circuits. Each of the first and second phase charge pump circuits includes a bootstrap capacitor. The bootstrap capacitors are switchingly connected by an equalization circuit that periodically transfers charge from a discharging capacitor to a charging capacitor, thereby reducing the charge that must be externally supplied to charge the charging capacitor.
