Abstract

Background: Multiplier is very important block which is being used in number of devices like DSP processor and microprocessors. Power consumption by multipliers decides the battery life of all these devices. Researchers are continuously striving for the multiplier which consumes less power but as the most dominant technology till now is CMOS, their efforts are not giving fruitful results due to physical constraints of CMOS device. Methods: In the proposed design used a reversible computing methodology and for circuit designing of multiplier used a QCA Cells. Findings: By combination of reversible computing and ancient Vedic method, a low power and high speed multiplier is proposed. Improvements: With this proposed technique, the Garbage outputs are reduced by 25%, numbers of gates are reduced by 5.40%, numbers of constant inputs are reduced by 6.89%, Quantum cost is reduced by 7.89% and TRLIC factor of this vedic multiplier is reduced by 16.89%.

Abstract

Objectives: Using slots and notches on the radiating element of planar antenna structure to enhance its performance. Methods/Statistical Analysis: Parametric analysis to optimize design parameters. Findings: The proposed antenna covers WiMax Band (Worldwide interoperability for microwave access) (3.43-3.83 GHz) and C-Band (4.105-4.285 GHz) applications at resonant frequencies of 3.6 GHz and 4.1 GHz with measured return loss value of -28.4 dB and -22 dB with the corresponding bandwidth of 400 MHz and 180 MHz has been achieved with VSWR less than two. The analytical results agree well with simulated and measured results. Application/Improvements: WiMax Band and C-Band.
