CASCODE SWITCHES INCLUDING NORMALLY-OFF AND NORMALLY-ON DEVICES AND CIRCUITS COMPRISING THE SWITCHES |
摘要 |
Switches comprising a normally-off semiconductor device and a normally-on semiconductor device in cascode arrangement are described. The switches include a capacitor connected between the gate of the normally-on device and the source of the normally-off device. The switches may also include a zener diode connected in parallel with the capacitor between the gate of the normally-on device and the source of the normally-off device. The switches may also include a pair of zener diodes in series opposing arrangement between the gate and source of the normally-off device. Switches comprising multiple normally-on and/or multiple normally-off devices are also described. The normally-on device can be a JFET such as a SiC JFET. The normally-off device can be a MOSFET such as a Si MOSFET. The normally-on device can be a high voltage device and the normally-off device can be a low voltage device. Circuits comprising the switches are also described.
