Abstract
PURPOSE: To accurately and simply measure characteristics in wide applied voltage range by discharging a capacitor charged in advance and applying the voltage across the terminals of the discharging capacitor to an element to be measured.
CONSTITUTION: A resistor 10 and a capacitor 9 connected in parallel with a semiconductor 1 to be measured such as a diode or the like are connected through a switch 11 to a variable DC power supply 2. When the switch 11 is opened, the charged capacitor 9 is discharged through the semiconductor 1 and the resistor 10. At this time the terminal voltage and current of the semiconductor 1 are measured by logarithmic converters 7, 8. Thus, the applied voltage lowering in exponential function can be reproduced in wide range continuously to thus measure accurately the voltage versus current characteristics of the element 1 to be measured.
