Abstract: In electronic applications, a synchronous relationship between the signals needs to be preserved for that phase measurement is required. In a Traditional electronic systems, the time measurement system is designed by using classical mixed signal approach. But it causes uncertainty in phase relationship between the recovered signals. To avoid this uncertainty, minute phase shift change register and phase measurement logic core is designed inside an FPGA with high resolution and precision in the range of few Pico seconds. The working principle present in the proposed system is systematic sampling, here subsamples are accumulated over the phase detector signal. The newly designed logic core can operate over a wide range of digital clock frequencies, ranging from a few kilohertz..........

Abstract: Nowadays ,due to the rapid development of multimedia and digital technology the transmission over public channel become more and more. Also the issues with the confidentiality and integrity of data increases in an alarming rate. So that the personal identification information or biometric signatures requires a security technique to protect from the any of the unauthorized access. Biometric signatures such as fingerprint , iris , palm print, gestures, handwritten signature and hand geometry have to be considered as an efficient tool for establishing the identity of an individual. Because they contain the unique characteristics of a person. So we go for the proposed biometric information security system using a three fold encryption technique............

Abstract: The objective of proposed system is to design the weighted based cell segmentation algorithm for multiple scan-chains BIST in order to reduce the average power consumption during the scan in of new test vectors, and to reduce the test application time. The technique is based on selecting the best group of cells to be connected in the same scan-chain. This group of cells should have the same or very close weight of logic 1's and 0's that will be optimal to get the highest fault coverage in a specified test length. Then each scan-chain input will be connected to an output of a combinational circuit located after the Linear Feedback Shift Register (LFSR) that will generate......

Abstract: A coupled line narrowband filter with second harmonic suppression is presented. A Novel narrow bandpass filter with sharp rejection at the lower frequency is proposed using open loop resonator. The stopband characteristics of complementary circular split ring resonator (CSRR) are studied and designed to suppress the second harmonic frequency. CSRR loaded with the proposed filter for harmonic suppression is demonstrated. The CSRR is optimized to create the required bandstop characteristics without affecting the desired bandpass frequency. The proposed CSRR configuration provides a harmonic suppression at 2.8 GHz and open loop resonator resonates at 1.5 GHz to bandpass the desired frequency. Results are compared with the full wave simulation analysis and presented.

Abstract: A modified hexagonal Sierpinski gasket-based fractal antenna is proposed for ultrawide-band (UWB) wireless applications. The designed antenna has miniaturized (36 48 mm2) and multiband characteristics. Two design guidelines, the partial ground plane technique and the circular annular ring patch on the substrate, are applied to improve impedance matching and radiation pattern characteristics. According to the simulation results, the proposed modi ed antenna has a re ection coefficient S11 of less than {15 dB, a linear phase of the reflection coefficient, 80% radiation efficiency, 2{4.5 dBi antenna gain, and omnidirectional radiation pattern properties over the full UWB spectrum (3.1{10.6 GHz). Simulated results obtained for this antenna show the expected good radiation behavior within the full 7.5-GHz UWB bandwidth.

Abstract: This paper presents different possibilities of configurable logic block (CLB) a hybrid cluster composed of look up table (LUTs) and universal logic gates (ULGs). A ULG is designed to realize logical functions with better efficiency compared to that of LUT based design. Pure LUT based architecture incurs a longer delay or doubles the area compared to the ULG based design. Since ULG is not capable of implementing all the classes of logic functions, a hybrid CLB that contains a mixture of LUTs and ULGs is the solution to address the generality problem and to achieve the benefits in the case of area, performance, and power. The power analyses the effect of different combinations of LUTs and ULGs in one basic logic element (BLE).The results show that, compared to pure LUT design, the experimented architecture design saves up to 17.1% logic power,52% time and 4.5% logic area..
