In this work the low power Gain Boosted Recycling Folded Cascode Operational Transconductance Amplifier (GB-RFC OTA) is designed and analyzed using 130nm CMOS technology. The design of the circuit is made schematically using design entry tool. Tanner Schematic Editor(S-Edit) is used for design entry. The generated net-list is simulated using T-Spice .For functional verification of the OTA circuits;DC, AC, transient analysis have been carried out. The proposed design is based on Recycling Folded Cascode topology.The recycling folded cascode OTA increases the effective transconductance of...

This work addresses the area of the data compression as it is applicable to the image processing. An analysis of the Discrete Cosine Transformation, Wavelet Transformation (Haar Transformation) and Simultaneous Encryption and Compression are made. These three image compression strategies are examined for their relative effectiveness. Finally a performance comparison is made between these techniques (on variety of Standard Test Images considering parameters such as data reduction ratios).

During the past two decades, photonic crystals, in particular photonic bandgap materials have became area of interest of many researchers. In this research, author has discussed the omnidirectional reflection and TE or TM mode filter properties of one-dimensional linear and nonlinear binary and ternary photonic crystal using transfer matrix method. Also, he has studied defect mode one-dimensional photonic crystals having a layer of non-linear material. Using Transfer Matrix method, the properties of such 1D binary photonic crystals have been theoretically studied. Introduction of a single...
