0_90°_SHIFTER

Published:2009/7/6 1:02:00 Author:May | From:SeekIC

Used in automatic plotter for measuring capacitance-voltage characteristics of Schottky barrier solar cells. Diode under test is connected as shown in block diagram. Phase of square-wave output from IC, can be shifted continuously from 0 to 90° by adjusting R3. Article gives ramp circuit and design equations.-J. T.
