Abstract
An interface circuit is disposed between a generator of control signals and a plurality of electronic switches in order to produce boosted voltage signals corresponding to the control signals for activating the electronic switches. To avoid the use of a capacitor with a high capacitance and thus to reduce an area of the integrated circuit, the interface circuit includes a generator of activation signals and a plurality of voltage multipliers each having an input connected to an output of the control signal generator, an output connected to at least one terminal for activating an electronic switch and two control terminals connected to an activation signal generator. Each voltage multiplier includes MOS transistors operatively coupled in series between the input and the output. The MOS transistors operate in response to the activation signals to produce a boosted voltage on the capacitor.
