This paper describes the speed of the design is limited by size of the transistors, parasitic capacitance and delay in the critical path. Power consumption and speed are two important but conflicting design aspects; hence a better metric to evaluate circuit performance is power delay product (PDP).The driving capability of a full adder is very important, because, full adders are mostly used in ...
This paper presents hardware-efficient Delta Sigma linear processing circuits for the next generation low-power VLSI devices in the Internet-of-things (IoT). We first propose the P-N (positive-negative) pair method to manipulate both the analog value and length of a first-order Delta Sigma bit sequence. We then present a binary counter method. Based on these methods, we develop Delta Sigma doma...
This paper presents the design of high-speed full adder circuits using a new CMOS mixed mode logic family. The objective of this work is to present a new full adder design circuits combined with current mode circuit in one unit to implement a full adder cell. This paper also discusses a highspeed hybrid majority function based 1-bit full adder that uses MOS capacitors (MOSCAP) in its structure ...
The main objective of the thesis is to implement different architectures of 16-bit adders such as; Ripple Carry Adder (RCA), Manchester Carry Chain Adder (MCCA) and Kogge Stone Adder (KSA), in 65nm CMOS technology and to study their performance in terms of power, operating frequency and speed at near threshold operating regions. The performance of these adders are evaluated and compared with ea...
Addition forms the basic structure for many processing operations like counting, multiplication, filtering etc. Adder circuits that add two binary numbers are of great interest for many designers. The simplest approach to design an adder is to implement gates to yield the required logic function. Carry-look ahead adder is a major functional block in arithmetic logic unit due to its high speed o...
An important arithmetic component of “Arithmetic and Logic Unit” or ALU is reconfigured in this paper, known as “Full-Adder-Subtractor”, where an advance low-power, high-speed nano technology “QCA” with electro-spin criterion used reversibility the advancement multilayer 3D circuitry. In modern digital world, selected nano-sized effective alternative widely “CMOS Technology” because all limitat...
The overall view of this paper is to attain high speed, low power full adder cells with alternative logic cells that lead to have reduced power delay product. Two high-speed and low-power full adder cells designed with an alternative internal logic structure and pass-transistor logic styles that lead to have a reduced power-delay product (PDP). We carried out a comparison against other full-add...
Carry free arithmetic using higher radix number system such as Redundant Binary Signed Digit can be used to meet the demand for computers operating at much higher speeds. The computation speed can also be increased by using the suitable design of adder and multiplier circuits. Fast RBSD adder cells suggested by Neelam Sharma in 2006 using universal logic are modified in the proposed design by r...
