InP-based high-performance monostable bistable transition logic elements (MOBILE's) using integrated multiple-input resonant-tunneling devices

MOBILE's (monostable-bistable transition logic elements), which have the advantages of multiple-input and multiple-function, are demonstrated in InP-based material system using monolithic integration of resonant-tunneling diodes and high electron mobility transistors, The high peak current density, high peak-to-valley ratio, and high transconductance, which are required for high-performance MOBILE's, are demonstrated in this InP-based material system, A fabricated MOBILE with three-input gates having 1:2:4 width ratio can perform weighted-sum threshold logic operation, and has a wide range of applications in new computing architectures, such as neural networks.
