AN ELECTRONIC SYSTEM FOR MEASURING THE ELECTRICAL CHARACTERISTICS OF NONLINEAR DEVICES
Abstract
An electronic system for obtaining the electrical characteristics of non-linear devices is described. Three modes of operation provide the I-V curve of the sample and either the differential conductance or resistance as a function of sample bias. A simple feedback system is shown to be particularly advantageous for determining the conductance of low impedance devices. A theoretical analysis provides an algorithm for separating the resistive and reactive components of the sample admittance and gives criteria for conditions of optimum stability and minimum noise. Finally the measured characteristics of a number of devices are shown to illustrate the capability of the instrument.
