Weighted sum threshold logic operation of MOBILE (monostable-bistable transition logic element) using resonant-tunneling transistors

The functional operation of the MOBILE (monostable-bistable transition logic element) has been studied using multiple-input logic gates. The MOBILE uses two resonant-tunneling transistors (RTTs) connected in series and driven by an oscillating bias voltage to produce a mono-to-bistable transition of...

Description
Summary:The functional operation of the MOBILE (monostable-bistable transition logic element) has been studied using multiple-input logic gates. The MOBILE uses two resonant-tunneling transistors (RTTs) connected in series and driven by an oscillating bias voltage to produce a mono-to-bistable transition of the circuit. A MOBILE having three input gates with a 1:2:4 width ratio can distinguish all 8 (2/sup 3/) input patterns corresponding to each weighted sum, depending on the threshold value selected by the control gate. The results confirm the realization of the weighted sum threshold logic operation of input signals.< >
