Abstract
An integrated circuit is provided, which includes a transistor device under test, an AC drive circuit, an AC bias circuit and a DC bias circuit. The AC drive circuit generates an AC drive signal. The AC bias circuit biases the transistor device under AC bias conditions in response to the AC drive signal. The DC bias circuit biases the transistor device under DC bias conditions. A switch circuit selectively couples the transistor device to the AC bias circuit in an AC stress mode and to the DC bias circuit in a DC measurement mode.
