According to the soft-switching pulsed SAW (Submerged arc weld) weld power supply based on the double closed-loop constant current control mode, a small signal mathematic model of main circuit of soft-switching SAW inverter was established by applying the method of three-terminal switching device modeling method, and the mathematic model of double closed-loop phase-shift control system circuit ...
Instability of SRAM memory cells derived from the process variation and lowered supply voltage has recently been posing significant design challenges for low power SoCs. This paper presents a boosted word line voltage scheme, where an active bodybiasing controlled boost transistor generates a pulsed word line voltage by capacitive coupling only when accessed. Simulation results have shown that ...
This paper describes the Differential Pass Transistor Pulsed Latch (DPTPL) which enhances D-Q delay and reduces power consumption using NMOS pass transistors and feedback PMOS transistors. The proposed flip-flop uses the characteristic of stronger drivability of NMOS transistor than that of transmission gate if the sum of total transistor width is the same. Positive feedback PMOS transistors en...
Zirconium oxide and tantalum oxide films were deposited in an inverted cylindrical magnetron cathode using high power pulsed sputtering. Average power densities were between 5 and 7 W/cm2 and peak power densities were in the range of 0.5 kW/cm2. In all of the experiments the oxygen was introduced using flow control, and the current and voltage waveforms of the HPPMS supply changed in a reproduc...
As part of a new heavy ion preinjector that will supply beams for the Relativistic Heavy Ion Collider and the National Aeronautics and Space Administration Space Radiation Laboratory, construction of a new electron beam ion source (EBIS) is now being completed. This source, based on the successful prototype Brookhaven National Laboratory Test EBIS, is designed to produce milliampere level curre...
