Abstract
A high-voltage switch has a high-voltage input terminal, receiving a high voltage, and an output terminal. A pass transistor, having a control terminal, is connected between the high-voltage input terminal and the output terminal. The output of a voltage-multiplying circuit of the charge-pump type is connected to the control terminal. The voltage-multiplying circuit is of a symmetrical type, has first and second charge-storage means, receiving a clock signal of a periodic type, and has a first circuit branch and a second circuit branch, which are symmetrical to one another and operate in phase opposition with respect to the clock signal.
