Abstract:
1. A two-phase charge pump capable of being controlled by a first clock signal having a first phase and a second clock signal having a second phase, the first and second clock signals being out-of-phase and taking alternatively a first value and a second value during consecutive phases, the charge pump comprising: a sequence of cascade-connected stages that each have a first section and a second section, each of the first and second sections including: wherein in each of the stages, the control terminal of the controlled switch of the first section is directly connected to the control terminal of the controlled switch of the second section, each of the first sections further includes a first control circuit coupling the control terminal with the output terminal of the first section during the first phase, and each of the second sections further includes a second control circuit coupling the control terminal with the input terminal of the second section during the second phase.
