1. An apparatus comprising:
a circuit coupled between a supply line, a return line, and a terminal, the circuit to provide an oscillating signal to the terminal, the circuit comprising:
a first switch to couple the supply line with the terminal;
a second switch to couple the return line with the terminal;
a first inductor coupled between the first switch and the terminal;
a second inductor coupled between the second switch and the terminal;
a first diode coupled between the return line and an internal node of the first switch and the first; inductor, wherein the first diode is coupled in parallel with a first circuit that includes the first switch and the first inductor; and
a second diode coupled between the supply line and an internal node of the second switch and the second inductor, wherein the second diode is coupled in parallel with a second circuit that includes the second switch and the second inductor.
