Abstract

Circuits for protecting devices, such as gallium nitride (GaN) devices, and operating methods thereof are described. Such circuits may include a temperature sensor configured to sense the temperature of at least a portion of a device, and a phase shifter configured to shift the phase of the signal output by the device, when the sensed temperature is outside a safe temperature range, e.g., above a predefined temperature threshold. The phase may be shifted discretely or continuously. These circuits safeguard devices from damaging operating conditions to prolong the operating life of the protected devices.
