Schottky diodes with high series resistance: Limitations of forward <i>I</i>-<i>V</i> methods

Abstract

Some methods have been proposed to deduce the value of Schottky parameters from forward I-V characteristic even in the presence of a large series resistance. In this paper, some well-known methods have been applied to experimental data of a real diode and to computer calculated curves. A comparison is made between these methods and the standard procedure. Some indications are given on the validity and the main limitations of all these techniques.
