  • Patent number: 10636728
    Abstract: A semiconductor device includes field-effect transistor having a gate, a drain, and a source. A first clamping circuit is connected between the drain and the gate. The first clamping circuit has a first clamp voltage that is lower than a source-to-drain breakdown voltage of the field-effect transistor. A first resistor in the device has a first end connected to a first node between the first clamping circuit and the gate. A second clamping circuit is connected between the drain and a second end of the first resistor. The second clamping circuit has a second clamp voltage is higher than the first clamp voltage and lower than the source-to-drain breakdown voltage.
