This paper proposes two reversible logic gates, HNFG and HNG. The first gate HNFG can be used as two Feynman Gates. It is suitable for a single copy of two bits with no garbage outputs. It can be used as “Copying Circuit” to increase fan-out because fan-out is not allowed in reversible circuits. The second gate HNG can implement all Boolean functions. It also can be used to design optimized add...

In this paper, the various low power delay product full adder circuits have been analyzed. The adder is the fundamental blocks of any arithmetic circuit, so even a small reduction power or delay leads to improved performance of the circuit with optimal power saving. A 10T adder technique is the famous low power delay product full adder circuits with minimum transistor count. A new 10T technique...

A power-efficient 8-bits digital adder using the new arithmetic A2 redundant binary representation is presented. This structure is very suitable for implementation in VLSI of mixed-signal circuits built around Multiplier Digital to Analog Converter (MDAC) cells. Using a reduced transistor count Full-Adder cells shows that our approach significantly reduces the power consumption of such adders c...

The Wallace Multiplier is mainly used in the Arithmetic & Logic Unit (ALU) to perform the scientific computation in processors, controller etc... The existing multiplication technique like booth multiplier, array multiplier etc requires more time in multiplications. Hence Wallace Multiplier has been designed by using the parallel process to reduce the delay. The regular Wallace Multiplier requi...

A specifically designed aza-starphene molecule is presented where contacting one, two, and/or three single Al adatoms allows this to function as a “3-inputs & 2-outputs” digital full adder on Au(111) surface. Sequentially positioning with atomic precision interact aza-starphene, inputs one classical digit per Al, which converted quantum information by the molecule. The intramolecular logical ca...
