Abstract
A charge pump circuit comprises a first bipolar transistor device and a second bipolar switching device arranged in a differential pair configuration. A first terminal of each of the first and second bipolar switching devices are coupled to a supply. A second like terminal of each of the first and second bipolar switching devices are coupled together and to ground potential via a pulsed current source. A field effect switching device is also provided and the first terminal of the first bipolar switching device is coupled to the voltage supply via the field effect switching device.
