Abstract
A charge pump circuit has a charge pump having at least two switched current sources arranged in series. The difference between the currents produced in the two switched current sources contributes to the output current from the charge pump. At least one of the two current sources is controlled by means of a control signal. A control circuit produces the control signal for the at least one controlled current source such that the currents produced in the two current sources are regulated to the same value.
