Abstract
A charge pump has two inputs, each for an input clock signal, and an output for the output of a pumped output potential. Two pumping capacitors are connected to the inputs. Second electrodes of the pumping capacitors are in each case connected via a first circuit module to a supply potential (ground) and via a second circuit module to the output. Also present is a controllable short-circuiting element, the controllable path of which is disposed between the second electrodes of the two pumping capacitors.
