Abstract
The present disclosure provides methods for testing and evaluating electrical parameters of electronic circuits. An exemplary method includes providing a device-under-test electrically coupled to a testing apparatus; and determining an optimum value of a first electrical parameter and an optimum value of a second parameter by testing the device-under-test according to a set of first electrical parameter values and a set of second electrical parameter values. The optimum value of the first electrical parameter and the optimum value of the second parameter are determined based on an electrical noise response of the device-under-test.
