Abstract
This application relates to a circuit for determining whether a first transistor device is in a predetermined operation mode. The circuit comprises comprising: a second transistor device, wherein control terminals of the first and second transistor devices are connected, and one of input and output terminals of the first transistor device is connected to the other one of input and output terminals of the second transistor device, a buffer amplifier connected between the one of input and output terminals of the first transistor device and the other one of input and output terminals of the second transistor device, and circuitry for determining whether the first transistor device is in the predetermined operation mode based on an indication of a current flowing through the second transistor device. The application further relates to a method of determining whether a first transistor device is in a predetermined operation mode.
