  • DEVICE AND METHOD FOR CHARACTERIZING THE CURRENT COLLAPSE OF GAN TRANSISTORS
    Publication number: 20250298069
    Abstract: A device for evaluating a dynamic resistance in a conducting state of a GaN-based transistor. The device including a test circuit provided with a circuit, the GaN-based transistor, forming an arm of the circuit, the device being provided with a stage for controlling the switch elements of the circuit to alternately set the switch elements of the circuit in a first configuration and then in a second configuration, the control stage being configured to trigger a connection of a drain-source voltage measuring stage to the GaN-based transistor after the circuit is set in the first configuration, and to trigger a disconnection of the drain-source voltage measuring stage from the GaN-based transistor before the circuit is set in the second configuration.
