Abstract: A driver circuit may include a first inductor with a first terminal coupled to a first voltage terminal and a first switch with a first and a second terminal. The first terminal of the first switch may be coupled to a second terminal of the first inductor via a first node and the second terminal of the first switch may be coupled to a second voltage terminal. Moreover, the driver circuit may include 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.
