OPTICAL EX-OR GATE

Avireni Srinivasulu, Sivadasan Kottayi

Abstract


The paper explains Optical EX-OR gate, implemented using unijunction transistors (UJT), Light emitting diodes (LED) and Photo-resistors (LDR) which works in 1.8Vdc instead of 3Vdc. The power dissipation of the designed gate is only 3 mW. This optical gate finds application in the field of mechatronics, Instrumentation and Fiber optics systems where intrinsic safety is of prime importance rather than speed of operation6
