Abstract
A device includes a controllable current source connected between a first node and a first terminal coupled to a cathode of a controllable diode. A capacitor is connected between the first node and a second terminal coupled to an anode of the controllable diode. A first switch is connected between the first node and a third terminal coupled to a gate of the controllable diode. A second switch is connected between the second and third terminals. A first diode is connected between the third terminal and the second terminal, an anode of the first diode being preferably coupled to the third terminal.
