Abstract: An adaptive clamp circuit includes a clamp circuit and a clamp control circuit. The clamp circuit includes a first transistor, a second transistor, and a variable resistor. The first transistor includes a first current terminal, a second current terminal, and a control terminal. The first current terminal is coupled to a switching terminal. The second current terminal is coupled to a ground terminal. The second transistor includes a first current terminal, a second current terminal, and a control terminal. The first current terminal of the second transistor is coupled to the control terminal of the first transistor. The second current terminal of the second transistor is coupled to the switching terminal. The variable resistor is coupled between the control terminal of the second transistor and the ground terminal. The clamp control circuit is coupled between the switching terminal and the variable resistor.

Abstract: A circuit includes a transistor, a first driver, a second driver, and a delay circuit. The transistor includes an array of transistor cells partitioned into a first switch and a second switch. The first driver is configured to control the first switch. The second driver is configured to control the second switch. The delay circuit is coupled between the first driver and the second driver. The delay circuit is configured to delay closure of the second switch until the first switch is closed and a voltage across the first switch is less than a predetermined voltage.
