Claim 0:
1. A circuit comprising:
a power supply node;
a power supply reference node;
a protection circuit comprising a first output terminal and first and second series of n-type high electron mobility transistors (HEMTs) coupled between the power supply node and the power supply reference node; and
a gate driver comprising a second output terminal and third through fifth series of n-type HEMTs coupled between the power supply node and the power supply reference node,
wherein
the first series of n-type HEMTs is configured to control a first voltage on a first node responsive to a power supply voltage on the power supply node,
the second series of n-type HEMTs is configured to control a second voltage on the first output terminal responsive to the first voltage,
the third series of n-type HEMTs is configured to control an internal signal on a second node responsive to the second voltage and to an input signal,
the fourth series of n-type HEMTs is configured to control a third voltage on a third node responsive to the internal signal, and
the fifth series of n-type HEMTs is configured to control an output signal at the second output terminal responsive to the internal signal and the third voltage.
