Abstract:
A novel optoelectronic resonant tunneling logic gate, OE MOBILE, is proposed and its basic logic functions such as NOT, NOR, NAND, OR, and AND are confirmed for optical inputs.
The fundamental idea is to use optical inputs to determine the logic level of the gate which consists of two serially connected resonant tunneling transistors (RTTs) with a p + /n-junction gate.
The OE MOBILE is operated by oscillating bias voltage to employ monostable-bistable transition. At the time when the transition occurs, the optical inputs are applied by illuminating the RTTs to control their peak currents and consequently to determine the output logic levels.
The power of an optical input for logic operations is as small as 5 µW owing to the operation based on monostable-bistable transition. It should be pointed out that the functions of an OE MOBILE can be changed between NOR and NAND by changing the control terminal voltage.
