Sub-threshold is a new paradigm in the digital VLSI design today. In Sub-threshold region, transistors are operated in sub-threshold voltage. This paper examine the Carry Look Ahead (CLA) Adder with dual mode logic (DML)principle, in which gates are operated in sub-threshold regime and comparison of results with Conventional basic Carry look ahead adder . The number of gates in CLA is 5 includi...
The method of Logical Effort is an easy way to estimate the delay in a CMOS circuit. In this work application of Logical Effort on transistor level analysis of 32-bit heterogeneous adder architecture is designed and presented. Heterogeneous architecture consists of concatenation of four different sub adders (Ripple Carry, Carry Look Ahead, Carry Skip and Carry Select Adder) to design an adder u...
High Speed and Independent Carry Chain Carry Look Ahead Adder (cla) Implementation Using Cadence-eda
In this paper focuses on carry -look ahead adders have done research on the design of high-speed, low-area, or low-power adders. Addition is the fundamental operation for any VLSI processors or digital signal processing. The main objective of this paper is to reduce the propagation delay and gate count of the Carry look-Ahead Adder (CLA).Which will also reflect in the reduction of area and powe...
This paper presents a novel approach for theoretical estimation of power consumption in digital binary adders. Closed-form expressions for power consumption of four different types of binary adders – the ripple-carry adder, the Manchester adder, a multiplexor-based carry-select adder and an efficient tree-based look-ahead adder – are derived in terms of word-length and pre-computed technologysp...
In this paper we have find great applicability in RNS implementation for the Diminished-one modulo 2n+1 Adder using Circular Carry Selection (CCS) circuit. This adder presents a modulo addition of different bit values for n = 8, 12, 16, 24, 32, 48, 64. We are using the Diminished-one criteria using Circular Carry Selection (CCS) technique for the proposed modulo adder. The circuit design of pro...
