The present disclosure provides an apparatus for measuring dynamic on-resistance of a nitride-based device under test (DUT) comprising a control terminal connected to a controller being configured to generate a control signal to switch on and off the DUT. The apparatus comprising a first clamping module, a second clamping module and a driving module. The driving module is configured to sense a state change of the DUT and generate a control signal to switch on and off the first clamping module based on the state change of the DUT such that when the DUT is at an on-state, an output voltage across the first and second output nodes is clamped to indicate a drain-source voltage of the DUT. The provided apparatus can address the overshoot issues in measurement of dynamic on-resistance of GaN device.
