Abstract
A switch having a drain terminal, a source terminal and a control terminal. The switch comprises a normally-on device including a first terminal, a second terminal, and a control terminal, a normally-off device including a first terminal, a second terminal, and a control terminal, and a clamp circuit. The first terminal of the normally-on device is the drain terminal of the switch and the control terminal of the normally-on device is coupled to the source terminal of the switch. The control terminal of the normally-off device is coupled to the control terminal of the switch. The second terminal of the normally-off device is the source terminal of the switch, and the first terminal of the normally-off device is coupled to the second terminal of the normally-on device. The clamp circuit coupled across the normally-off device and comprises a first transistor coupled to the first terminal of the normally-off device.
