Simple monostable multivibrators using EX-OR/EX-NOR gates

Abstract

Two simple differential-type monostable multivibrators are proposed and demonstrated in this letter, where the first configuration operated under positive triggering mode utilizes EX-OR gates and the second configuration operated under negative triggering mode employs EX-NOR gates. Both realization methods make use of CMOS logic gates connected with a few passive elements to form as switching circuits. Experimental results show that the ranges of the output pulse widths are from several microseconds to milliseconds. © 2010 The Institute of Electrical Engineers of Japan.
