Abstract. An Electro-Optical Hybrid Logic Gate is defined as a circuit which accepts
either electrical or optical signals and produces both electrical and optical signals. This
paper explores the feasibility to develop universal hybrid NOR and NAND gates which
can be used for implementing any basic gate like AND, OR, or any complex logic
function. These hybrid logic gates are proposed and implemented using phototransistors
and LEDs. The logic circuits are found to be working satisfactorily for the defined logic
levels.
Keywords: hybrid circuits, hybrid logic gates, opto-electronics, hybrid opto-electronics,
electro-optical logic gates.
