ABSTRACT:
A circuit configuration for a charge pump includes a first series circuit of n integrators and a second series circuit of n further integrators that are connected up to one another via feedback paths. The individual integrators may be configured in the form of controllable integrators which, when used in a voltage regulator circuit, are set depending on the output signal of a regulating amplifier. In particular, the frequency of the charge pump can be adapted in a load-dependent manner with the aid of the controllable integrators.
