Claim 18:
19. A method of operation of an electronic circuit inside an GaN integrated circuit chip, the electronic circuit comprising a GaN power switch including a drain node, a source node, and a gate, the gate for receiving a driving electrical signal from an output of a driver circuit in the electronic circuit, and a bias-less Miller clamp protection circuit electrically coupled to the output of the driver circuit and to the gate of the GaN power switch, the method comprising:
coupling a parasitic Miller turn-on signal from the drain node into the bias-less Miller clamp protection circuit; and
clamping, by the bias-less Miller clamp protection circuit while a supply voltage for the driver circuit and for the protection circuit is absent, the gate of the semiconductor switch device to prevent the GaN power switch turning from an off state to an on state, in response to the parasitic Miller turn-on signal being electrically coupled into the bias-less Miller clamp protection circuit.
