Abstract: A charge pump for negative voltages, having at least one stage including a high-voltage terminal and a low-voltage terminal; a first branch and a second branch, which are symmetrical and are connected between the high-voltage terminal and the low-voltage terminal and each of which comprises a respective first transistor and a respective second transistor. The first and the second transistors are all triple-well MOS transistors of one and the same polarity type.
