Abstract
An apparatus for measuring a device current of a device under test (DUT) includes a first circuit including a first terminal for coupling to a first connection terminal of the DUT. The first circuit is configured to supply a first test voltage for the first terminal and to output a first output voltage sensed at the first terminal. The apparatus further includes a second circuit having a second terminal for coupling to a second connection terminal of the DUT. The second circuit is configured to supply a second test voltage for the second terminal and to output a second output voltage sensed at the second terminal. The apparatus further includes a third circuit configured to determine the device current of the DUT based on the first output voltage, the second output voltage, the first test voltage and the second test voltage. The first circuit and the second circuit are identical.
