1. A circuit for operating a half-bridge, comprising:
- a first multiplier circuit configured;
to multiply a first signal by a first factor to provide a turn-on signal configured to turn on a first switch of the half-bridge; and
to multiply the first signal by a second factor to provide a turn-off signal configured to turn off a second switch of the half-bridge;
wherein the first factor and the second factor are chosen so that the second switch is turned off before the first switch is turned on; and
a first generating unit configured to provide the first signal, wherein the first generating unit comprises a first current controlled current source controlled by a control current.

Abstract
A circuit for operating a half-bridge is provided. The circuit may include a first multiplier circuit. The first multiplier circuit may be configured to multiply a first signal by a first factor to provide a turn-on signal. The turn-on signal may be configured to turn a first switch of the half-bridge on. The first multiplier circuit may be further configured to multiply the first signal by a second factor to provide a turn-off signal. The turn-off signal may be configured to turn a second switch of the half-bridge off. The first factor and the second factor may be chosen so that the second switch is turned off before the first switch is turned on.

8. An integrated circuit, comprising:
-
a half-bridge circuit, wherein the half-bridge circuit comprises a first switch and a second switch coupled in series to each other, wherein the first switch and the second switch have majority carriers of opposite polarity; a half-bridge driver circuit, wherein the half-bridge driver circuit is configured; to multiply a first current by a first factor to provide a first turn-on current, wherein the first turn-on current is configured to turn-on the first switch; to multiply the first current by a second factor to provide a first turn-off current, wherein the first turn-off current is configured to turn-off the second switch; to multiply a second current by a third factor to provide a second turn-on current, wherein the second turn-on current is configured to turn-on the second switch; and to multiply the second current by a fourth factor to provide a second turn-off current, wherein the second turn-off signal is configured to turn-off the first switch; wherein the first current and the second current are provided alternately; the first factor and the second factor are chosen so that the second switch is turned off before the first switch is turned on; and the third factor and the fourth factor are chosen so that the first switch is turned off before the second switch is turned on.

9. A method for operating a half-bridge, comprising:
-
providing a first signal from a first generating unit, wherein the first generating unit comprises a first current controlled current source controlled by a control current; scaling the first signal to provide a first turn-on signal, wherein the first turn-on signal is configured to turn on a first switch of the half-bridge; applying the first turn-on signal to the first switch; scaling the first signal to provide a first turn-off signal, wherein the first turn-off signal is configured to turn off a second switch of the half-bridge; and applying the first turn-off signal to the second switch; wherein the first turn-on signal and the first turn-off signal are scaled so that the first turn-off signal turns the second switch off before the first turn-on signal turns the first switch on. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
