1. A driver circuit comprising:
a first inductor with a first terminal coupled to a first voltage terminal,
a first switch with a first and a second terminal, wherein the first terminal of the first switch is coupled to a second terminal of the first inductor via a first node and the second terminal of the first switch is coupled to a second voltage terminal,
a diode with a first terminal coupled to the first node,
an output terminal, and
a first capacitor with a first electrode coupled to a second terminal of the diode and a second electrode coupled to the output terminal,
further comprising a harvesting circuit coupled to at least one of the voltage terminals of the driver circuit and configured to regain energy.
