High Speed Delay-Locked Loop for Multiple Clock Phase Generation
In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...
متن کاملDevelopment Technology for Welding in Mig-mag Shielding Gas Environment
The information system is a coherently structured assembly, made of electronic computing and communication equipments, software, processes, automated and manual procedures, used as automatic data processing tool within a field of activity. In the process of welding in shielding gas environment with fusible electrode, there are used either inert or active gases. Therefore, we make the distinctio...
متن کاملArc Shape Characteristics with Ultra-High-Frequency Pulsed Arc Welding
Arc plasma possesses a constriction phenomenon with a pulsed current. The constriction is created by the Lorentz force, the radial electromagnetic force during arc welding, which determines the energy distribution of the arc plasma. Welding experiments were carried out with ultra-high-frequency pulsed arc welding (UHFP-AW). Ultra-high-speed camera observations were produced for arc surveillance...
متن کاملNumerical Investigation on the Effect of Tunnel Height on Drag Reduction in a High Speed Trimaran
There are different methods to reduce drag in high speed hulls. One of these methods is a change in the shape of the body by adding longitudinal side tunnels. In this paper it has been attempted to determine the influence of the tunnel height on hydrodynamic characteristics of the hull to achieving an optimum shape for the tunnel. To achieve this purpose, numerical simulation of the problem has...
متن کاملMag Welding Process - Analysis of Welding Parameter Influence on Joint Geometry
Quality of welded joint at MAG welding process depends of numbers of influences, like type and thickness of base metal, groove type, welding position etc., but the proper selection of welding parameters is also very important. Due to that, the analysis of weld bead geometry at MAG welding process with regard to weld current, voltage and weld speed (heat input) and the type and shielding gas flo...
