ABSTRACT:
An integrated control device for controlling a device such as a LED display or a miniature stepping motor for an electronic watch comprises at least one insulated-gate field effect transistor for controlling the supply of current to the element. The gate of the F.E.T. is connected to a control circuit including a voltage multiplier comprising a series-connected chain of rectifiers and a plurality of capacitors connected between the respective junctions between rectifiers and alternate inputs. High frequency signals of opposite phase are supplied to the inputs under control of an input control signal. Circuit means are provided for starting the action of the voltage multiplier at the beginning of an input control signal and for short-circuiting the output of the control circuit at the end of an input control signal.
