1. A device, comprising:
an electronic device including:
a controllable current source coupled between a first node and a first terminal, the first terminal being coupled to a cathode of a controllable diode;
a capacitor coupled between the first node and a second terminal, the second terminal being coupled to an anode of the controllable diode;
a first switch coupled between the first node and a third terminal, the third terminal being coupled to a gate of the controllable diode;
a second switch coupled between the second terminal and the third terminal; and
a first diode coupled between the third terminal and the second terminal, an anode of the first diode being coupled to the third terminal.
