A novel contribution to the RTD-based threshold logic family

Many logic circuit applications of resonant tunneling diodes are based on the MOnostable-BIstable Logic Element (MOBILE). Threshold logic is a computational model widely used in the design of MOBILE circuits, i.e. these circuits are built from threshold gates. More recently, generalized threshold gates, also suitable to be realized with MOBILE RTD structures, are being investigated. In this paper we propose a novel MOBILE circuit topology obtained by exploiting threshold logic concepts and properties. A comparison in terms of speed and power performance between the proposed topologies and previous reported ones is carried out.
