Full adderQCA designerConventional CMOS Technology is losing its efficiency to fulfil the needs of this technically super advanced era in which we need devices with lesser power, lesser area and higher speed than ever. CMOS will reach its limitation due to concepts of fundamental physics. If we ...
DESIGN OF FULL-ADDER BASED ON a-SiC:H TECHNOLOGYManuel Augusto Vieira
From the logic diagram of the full adder using half adders, it is clear that we require two XOR gates, two AND gates and one OR gate for the implementation of a full adder circuit using half-adders.However, the implementation of full adder using half adder has a major disadvantage that ...
It is found that, full adders designed with adiabatic logic styles tends to consume very low power in comparison to full adder designed with static CMOS logic. Under certain operating conditions, one of adiabatic designs of full adder achieves upto 74% power saving in comparison to the full ...
A systematic model for all-optical full adder as well as full subtractor is proposed based on principle of Mach Zehnder Interferometer and using Semiconductor Optical Amplifier (MZI-SOA) configuration. MZI plays a role for ultra fast all-optical signal processing, here the non-linear property of ...
In this tutorial, we will learn about the half and full adders, designing of a full adder using half adder in Digital Electronics.
Digital circuits are implemented in QCA using majority logic. Adder and subtractor are used widely in almost every data processing system. For efficient hardware implementation, a single hardware can be used to perform both addition as well as subtraction. In this paper, a novel majority logic ...
By analysing the output characteristics of individual pass transistors in a transmission gate (TG) based CMOS full adder, it is possible to use fewer transistors to implement addition. Various simplified full adders with different numbers of transistors are tested using Pspice simulation. Comparison of...
In this paper, we present a design of Full Adder circuit using AVL techniques for low power operation. The approach for the design is based on XOR/XNOR & Transmission gate for single bit as hybrid design .By using this approach Full Adder is being designed using 12 transistors. We can ...
The comparison of the energy-efficient curves allows us to make a simple and effective comparison as well as to identify the best one-bit full adder topologies. Keywords: CMOS digital integrated circuits; ripple carry adders; full adders; energy-efficient curve; energy-delay space; VLSI...
