1. A circuit for generating a control voltage across a pair of output terminals for controlling a switch having an input terminal, a reference terminal, and a control terminal, said circuit comprising:

  • a capacitor;

    a first pair of switches adapted to couple said capacitor to an input voltage source during a first time interval;

    a second pair of switches adapted to couple said capacitor to said pair of output terminals during a second time interval, non-overlapping with respect to said first time interval; and

    a control circuit providing a first control signal to said first pair of switches in response to the voltage across said capacitor and providing a second control signal to said second pair of switches.
