Abstract

A method for determining an emission coefficient of a device under test (DUT) using a test circuit comprises coupling a parameter measurement circuit associated with the test circuit to an input pin associated with the DUT, wherein the input pin is coupled to a diode element within the DUT and performing voltage and current measurements associated with the input pin using the parameter measurement circuit. In some embodiments, the method further comprises determining a plurality of contact resistance values respectively based on the voltage and current measurements and an emission coefficient estimate using a contact resistance estimation circuit; and determining an emission coefficient associated with the DUT based on the determined plurality of contact resistance values using an emission coefficient determination circuit.
