Improved nanopipelined RTD adder using generalized threshold gates

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 thres hold gates (TGs). This paper describes the design...

Descrição
Resumo: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 thres hold gates (TGs). This paper describes the design of full adders (FAs) using TG based circuit topologies. Both the selection of different MOBILE TG networks and the use of gates that can be considered extensions of the MOBILE TG are addressed. The FAs are applied to the design of nanopipelined carry propagations adders which are evaluated and compared to a previously reported one, showing advantages in terms of speed, power and power delay product.
