Abstract
A charge pump circuit includes a first capacitor having an input coupled to a first signal. A second capacitor has an input coupled to a second signal. A first diode has an anode coupled to an output of the first capacitor and a cathode coupled to an output of the second capacitor. A second diode has an anode coupled to the output of the second capacitor and a cathode coupled to the output of the first capacitor. A controllable switch has a control input coupled to the output of the second capacitor and couples the output of the first capacitor to an output of the charge pump circuit.
