In this paper, we compare four SRAM circuits. They are the conventional SRAM1, the SRAM2 with power switches on VSS line, the SRAM3 with switches on VDD line, and the SRAM4 with switches on both VDD and VSS lines, respectively. Among the four SRAMs, the SRAM2 shows the smallest amount of leakage, because its subthreshold leakage is most suppressed by its BODY and Drain-Induced Barrier Lowering ...

As a kind of congenital vascular malformations, Port Wine Stain (PWS) is composed of ectatic venular capillary blood vessels buried within healthy dermis. In clinic, Pulsed Dye Laser (PDL) in visible band (e.g. 585 or 595 nm) together with cryogen spray cooling has become the golden standard for treatment of PWS. However, due to the limited energy penetration depth of the PDL, deeply buried blo...

Abstract High-power continuous-wave single-frequency Er-doped fiber amplifiers at 1560 nm by in-band and core pumping of a 1480 Raman laser are investigated in detail. Both co- counter-pumping configurations studied experimentally. Up to 59.1 W output 90% efficiency were obtained the fundamental mode linear polarization co-pumped case, while less power achieved counter-pumped setup for addition...

We present for the first time a Nd:YVO(4) laser emitting at 1064 nm intracavity pumped at 912 nm by a Nd:GdVO(4) laser. We carried out a model to design the system properly, and laser performance was experimentally investigated. Intracavity sum-frequency mixing at 912 and 1064 nm was then realized in a BiBO crystal to reach the blue range. We obtained a cw output power of 155 mW at 491 nm with ...
