Variations of SNMs in Sub-threshold Circuits
Sub-threshold operation offers a compelling solution for ultra-low energy applications such as micro-sensors and embedded medical applications, where low energy needs are the primary concern instead of speed. By lowering the supply voltage below the transistors’ threshold voltage, we see a dramatic drop in energy consumption when compared to normal operations, but circuit instability and delay ...
متن کاملDesign of Carry Look Ahead Adder Using Sub Threshold Dual Mode Logic
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...
متن کاملDesign of Robust, Ultra Low-Power Efficient Full Adder Cell in sub-45nm Technologies
Nowadays, there is a need to design microelectronic circuits which utilizes less energy and small area because of extensive growth of portable devices like laptops, digital watches and personal communication devices like mobile phones, and continuous shrinking of technology node. Many applications require circuits of high throughput, small area and consume ultra-low power. In this regard, this ...
متن کاملEfficient Design of QCA Adder Structures
Optimizing arithmetic primitives such as quantum-dot cellular automata (QCA) adders is important for investigating high-performance QCA computers in this emerging nano-technological paradigm. In this paper, we demonstrate that QCA ripple carry adder and bit-serial adder designs actually outperform carry-look-ahead and carry-select adder designs because of the increase in required interconnects....
متن کاملDesign of Efficient Han-Carlson-Adder
In digital VLSI systems binary addition is the most significance arithmetic function. To a great extent adders are used as DSP lattice filter where the ripple carry adders are substituted by the parallel prefix adder to reduce delay. The requirement of adder is that it is fast and it has area efficient and low power consumption. In this the parallel prefix adder is introduced as speculative Han...
