ABSTRACT:
A charge pump assembly includes a storage capacitor having one terminal for a first supply potential and another terminal for pickup of an output potential. The assembly has one charge pump or two charge pumps being controlled by push-pull signals. Each charge pump includes a p-channel MOS transistor having a gate terminal being controlled by a first signal and having a drain-to-source path with one terminal being connected to the other terminal of the storage capacitor. A sliding capacitor has one terminal being connected to the other terminal of the drain-to-source path of the p-channel MOS transistor and another terminal being controlled by a second signal. An n-channel MOS transistor has a gate terminal being controlled by a third signal and a drain-to-source path being connected between a second supply potential and the one terminal of the sliding capacitor. A pulse shaper device is supplied by an oscillator device for generating the signals, in such a way that the p-channel MOS transistor is conducting only whenever the second signal is at a high level, and the n-channel MOS transistor is conducting only whenever the second signal is at a low level.
