Mk. Ravishankar et M. Satyam, OPTICALLY ELECTRICALLY (SYMMETRICALLY) TRIGGERABLE BISTABLE MULTIVIBRATOR/, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 43(7), 1996, pp. 610-612
An optically and electrically, symmetrically triggerable hybrid bistab
le multivibrator giving both optical and electrical outputs is propose
d, designed, and implemented using phototransistors, light emitting di
odes, etc. The circuit is found to be working satisfactorily at medium
frequency range.
