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.
Claims16
A driver circuit comprising:
- a first inductor comprising a first terminal coupled to a first voltage terminal;
- a first switch comprising a first terminal 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 comprising a first terminal coupled to the first node;
- an output terminal;
- and
- a first capacitor comprising a first electrode coupled to a second terminal of the diode and a second electrode coupled to the output terminal.
A method for providing a pulse, wherein the method comprises:
- setting a first switch into a conducting state, wherein the first switch couples a second terminal of a first inductor to a second voltage terminal;
- and wherein a first terminal of the first inductor is coupled to a first voltage terminal;
- and
- setting the first switch into a non-conducting state, wherein the second terminal of the first inductor is coupled via a diode to a first electrode of a first capacitor and a second electrode of the first capacitor is coupled to an output terminal at which an output voltage with a pulse is provided.
