This enables for example an abnormal temperature protection, lifetime monitoring or junction temperature control. This paper proposes an online junction temperature measurement based on the internal gate resistance as a temperature sensitive electrical parameter. A direct measurement of this resistance is not possible. Therefore, a high frequency signal is injected into the gate circuit to measure the gate circuit's impedance, which includes the temperature sensitive internal gate resistance. This paper focuses on a simple realization of this method. %@ 978-3-8007-4938-6
