ABSTRACT:
A charge pump circuit includes a pair of series switching devices coupled between an output node of the circuit and an input node. A power stage drives a charge transfer capacitor which is coupled to an intermediate node between the series switching devices. The power stage has an input coupled to the input node of the circuit, The power stage further includes a bootstrap capacitor for maintaining a conductive state during an entire half of a cycle of a period of oscillation of a local oscillator. The series switching devices may be driven in phase opposition by either a CMOS invertor or a pair of comparators.
