This Image compression using Discrete Wavelet Transform has got application in many filed like biomedical, agriculture, digital video compression, wireless networks. In this paper we present a parallel-pipelined architecture for lifting based two dimensional DWT. We have used lifting based wavelet filter for image compression. Overall area has been reduced by eliminating line buffer and frame buffer...
This paper shows the implementation and comparison of Carry Select Adder (CSA) using BEC (Binary Excess one Converter) and First Zero Finding (FZF) logic implementation techniques with optimization of the Full Adder (FA) cell by minimize number of transistors. The results have been analyzed and compared for implementation of both the above logic styles for 28T, 10T and 8T FA cells where as keeping...
In this paper the proposed design of RF MEMS capacitive switch is made of thin film of Au membrane and dielectric material of AlN. The advantages of using AlN as dielectric material rather than Si3N4, SiO2, Barium Strontium Titanate (BST) and HfO2 in terms of isolation and insertion loss are extensively discussed in paper. Actuation voltage required for the design is very low (4V), insertion loss...
The paper gives a review of already existing 3-T XOR cells and provides an optimized value of (W/L) on the basis of simulation results obtained, so as to improve the threshold loss problems present in the existing designs of 3-T XOR cells thus helping improve the driving capability, however the driving capability is not sufficient for large circuits like multipliers, hence has a scope for further...
