VARIABLE_0_180_DEG_PHASE_SHIFTER

Published:2009/7/20 6:54:00 Author:Jessie | From:SeekIC

Single low-cost pnp germanium transistor circuit gives any desired phase between 0 and 180 degrees, at constant amplitude, for frequencies up to 3 Mc, by varying values of C2 and R5. Values shown gives 90° shift for 200 cps. –J. J. Collins, Single Transistor Provides Low-Cost Phase Shifter, Electronics, 37:16, p 92.
