Abstract
Due to scaling of conventional MOS transistors, leakage currents are increasing which leads to increase in power dissipation. Increase in power dissipation puts limit on scaling. To overcome the power dissipation problem, conventional MOS transistors are replaced with FinFETs. FinFETs have low leakage currents which reduce power dissipation. In this paper the focus is on the implementation of different full adder circuits using FinFETs. Comparisons are made between CMOS and FinFET implementation of Hybrid Full Adder, 14 Transistor Full Adder, GDI based Full Adder, and 10 transistor Full Adder using 32 nm and 45 nm technology models. FinFET implementation achieves low power and high speed compared to CMOS implementation.

Continuous Overvoltage Characteristics of Surge Protected Power Strips

Volume 5 Issue 4 September - November 2017 Research Paper Continuous Overvoltage Characteristics of Surge Protected Power Strips Cengiz Polat* Assistant Professor, Department of Electrical and Electronics Engineering, Istanbul University, Istanbul, Turkey. Uzunoglu, C. P. (2017). Continuous Over Voltage Characteristics of Surge Protected Power Strips.  i-manager’s Journal on Circuits and Systems,  5(4), 1-7.  https://doi.org/10.26634/jcir.5.4.13938 Abstract Increasing applications of constantly developing electronic devices require delicate voltage and current protection. Although the electrical network is monitored continuously, undesired over currents and over voltages may occur on the distribution system due to failures. Most of the electronic switch gear is connected via surge protected power strips in indoor applications, where current protection is vital. Surge protected power strips are usually manufactured based on Metal Oxide Varistors (MOVs) ...

Reduced Wirelength-Based Low Power Performance of Multibit Flip-Flop

Volume 1 Issue 4 September - November 2013 Research Paper Reduced Wirelength-Based Low Power Performance of Multibit Flip-Flop M.Karthick*, S. Vijayakumar** *PG Scholar, Department of Electronics and Communication Engineering, Paavai Engineering College, Namakkal, India. **Associate Professor, Department of Electronics and Communication Engineering, Paavai Engineering College, Namakkal, India. Karthick, M. and Vijayakumar, S. (2013). Reduced Wire length-Based Low Power Performance Of Multibit Flip-Flop.  i-manager’s Journal on Circuits and Systems , 1(4), 22-26.  https://doi.org/10.26634/jcir.1.4.2593 Abstract Power reduction is a main parameter to design VLSI circuits. In this paper, to design a number of D-flip flop performing at the same time, the given clock signal is reduced using multi bit flip-flop. The multi bit flip flop is mainly used to improve the clock power for the given common clock signal and to reduce the switching power. This method is p...

A Review on Control strategies for LFC in Deregulated Scenario

Volume 1 Issue 1 December - February 2013 Review Paper A Review on Control strategies for LFC in Deregulated Scenario T. Anilkumar*, N. Venkata ramana** * Associate Professor, EEE Department, ACE Engineering College, Ghatkesar, Hyderabad, AP, India. ** Professor and Head of Deportment, EEE Department, JNTU Mantini, AP, India. Kumar, T. A., and Ramana, N., (2013). A Review On Control Strategies For LFC In Deregulated Scenario.  i-manager’s Journal on Circuits and Systems , 1(1), 27-36.  https://doi.org/10.26634/jcir.1.1.2197 Abstract In power system studies, Load frequency control is an important issue to supply sufficient and reliable electric power with good quality. The main objective of LFC is to maintain load frequency and tie-line power flow within permissible limits by adjusting megawatt output of LFC generators, so as to accommodate fluctuating load demands. This paper presents a brief review of different control techniques to researchers on design...
