Abstract
An electronic circuit, integrated circuit, and method for a bias-less Miller clamp protection circuit, electrically coupled to an output of a driver circuit and to an input gate of a semiconductor switch device, for dynamically protecting the semiconductor switch device from turning from an off state to an on state in response to a parasitic Miller turn-on signal at the gate, regardless of the bias-less Miller clamp protection circuit having, or lacking, a power supply that provides electrical power to the bias-less Miller clamp protection circuit. The semiconductor switch device can include one or more GaN switch devices. The bias-less Miller clamp protection circuit does not consume any current during normal operation of the electronic circuit and also does not cause any interference to the normal operation.
