A novel low power and low transistor count static energy recovery full adder (SERF) is presented in this paper. The power consumption and general characteristics of the SERF adder are then compared against three low power full adders; the transmission function adder (TFA), the dual value logic (DVL) adder and the fourteen transistor (14T) full adder. The proposed SERF adder design was proven to...

A standard cell based gate level synchronous full adder design is presented in this paper. The main highlight of the article is that the proposed full adder realization is found to be better in terms of power-delay product (PDP), even in comparison with the full adder element that has been made available as part of two commercial standard cell libraries viz. the high-speed 130nm Faraday (UMC) b...

Energy recovery technique has attracted interest of low power VLSI designers in recent years. This low power design technique has been proposed and discussed by many researchers. In this paper, we implemented energy recovery technique in the PSPICE using an 8-bit full adder circuit as an example. Full adder circuit has been widely used in arithmetic operations for addition, multipliers and Arit...

A performance analysis of 1-bit full-adder cell is presented. The adder cell is anatomized into smaller modules. The modules are studied and evaluated extensively. Several designs of each of them are developed, prototyped, simulated and analyzed. Twenty different 1-bit full-adder cells are constructed (most of them are novel circuits) by connecting combinations of different designs of these mod...

This paper mainly presents Mixed Gate Diffusion Input Full Adder based on static CMOS inverter topology. In this proposed mixed Full Adder topology, GDI Full adders are followed by inverters in the long Full Adder chain to improve the performances as compared to conventional single topology Full adder chain. For any circuits reducing the speed and power dissipation are the important constraints...

In this paper, we survey various designs of low-power full-adder cells from conventional CMOS to really inventive XOR-based designs. We further describe simulation experiments that compare the surveyed full-adder cells. The experiments simulate all combinations of input transitions and consequently determine the delay and power consumption for the various full-adder cells. Moreover, the simulat...

In any digital circuit surface area and power both are very important parameters. In this paper 4bit full adder using transmission gate is designed. To design 4bit full adder two methods are used. First is semi custom design method and second is full custom design method. In first semi custom design method a layout of 4-bit full adder is designed with available width and length of the transisto...

In this paper, five new multiplexer-based architectures for 1 -bit full adder circuit designs are proposed. Following these architectures, various full adder circuits can be built through different circuit implementations of multiplexers. For instance, in this paper, we demonstrate that by substituting each multiplexer with two transmission gates, a set of new full adder circuits are ready to b...

The proposed multiplexer-based novel 1-bit full adder cell is schematized by using DSCH2 and its layout is generated by using microwind VLSI CAD tool. The adder cell layout interconnect analysis is performed by using BSIM4 layout analyzer. The adder circuit is compared with other six existing adder circuits for parametric analysis. The proposed adder cell gives better performance than the other...
