555 Zero-Symmetric Bi-Directional Pulse Generator Circuit

Published:2011/5/1 10:01:00 Author:Robert | Keyword: Zero-Symmetric, Bi-Directional, Pulse Generator | From:SeekIC

As shown, this circuit can meet the requirements of the periodic pulse outputing symmetrically to the ground.Under the power voltage of +/-15V, it can output +/-11V bi-directional pulse. VT1, VT2 and R1~R4 make up the voltage shifting networks, using the floating power supply method to the IC 555. 555 and R5, R6, C2 make up the astable multivibrator, oscillation frequency is f=1.44/(R5+2*R6)C2 and it is about 90Hz.
