هدف از این تحقیق ایجاد پوشش آمورف پایه آهن روی قطعات فولادی توسط فرآیند پوشش دهی الکترواسپارک است. در پروژه حاضر ابتدا دستگاه پوشش دهی الکترواسپارک (esd) ساخته شد و سپس از آن برای انجام آزمایشات پوشش دهی استفاده گردید. در فرآیند esd به سبب ایجاد اختلاف پتانسیل بین الکترود و زیرلایه و تماس لحظه ای، تخلیه الکتریکی به شکل جرقه ایجاد می شود و به دنبال آن فلز از الکترود به قطعه کار منتقل می شود. این...
This tutorial paper reviews the state of knowledge of on-chip ESD (electrostatic discharging) protection circuit design for integrated circuits. The discussion covers critical issues in ESD design, such as, ESD test models, ESD failure mechanism, ESD protection structures, ESD device modeling, ESD simulation, ESD layout issues, and ESD influences on circuit functionality, etc. This review serve...
AIM The efficacy of pre-procedure oral proton pump inhibitor (PPI) administration for gastric endoscopic submucosal dissection (ESD) is unclear. This study evaluated oral PPI administration effectiveness on the day of ESD to prevent post-ESD bleeding. METHODS This study examined 55 patients who underwent ESD for gastric neoplasm. Group A comprised 31 patients who took rabeprazole sodium (RPZ)...
Background and study aims The adequate visualization of the dissection line, inside the submucosal layer, supposes the main challenging issue in ESD. For this reason, several counter traction methods have been developed focused on overcoming this handicap. One of which, Magnetic anchor guided - ESD (MG-ESD) is an attractive alternative. However, the usefulness of this approach has been scarcel...
تکنولوژی cmos در ابعاد نانو به طور گسترده ای در مدارات مجتمع rf مورد استفاده قرار می گیرد . تقویت کننده های کم نویز نیز اولین طبقه در ورودی گیرنده های بی سیم می باشند و بیشتر در معرض خرابی توسط تخلیه الکترواستاتیک ( esd) می باشند و باریک شدن لایه اکساید گیت در ابعاد نانو به طور جدی مقاومت در برابر esd را کاهش داده است، و طراحی مدارهای حفاظت esd را برای این بخش ضروری می کند . برای مقابله با خراب...
Esophageal endoscopic submucosal dissection (ESD) is technically difficult. To make it safer, we developed a novel method using overtube with a traction forceps (OTF) for countertraction during submucosal dissection. We conducted an ex vivo animal study and compared the clinical outcomes between OTF-ESD and conventional method (C-ESD). A total of 32 esophageal ESD procedures were performed by f...
Electrostatic discharge (ESD) protection design for high-speed input/output (I/O) interface circuits in a 130-nm CMOS process is presented in this paper. First, the ESD protection diodes with different dimensions were designed and fabricated to evaluate their ESD levels and parasitic effects in gigahertz frequency band. With the knowledge of the dependence of device dimensions on ESD robustness...
polysilicon diodes to trigger ESD protection device is proposed to achieve excellent on-chip ESD protection. Design methodology of this novel ESD clamp circuit has been derived in detail. Some controlled factors in the novel ESD clamp circuit can be exactly calculated to design a suitable ESD clamp circuit for different power supply applications. By adding this efficient power-rail ESD clamp ci...
Abstract On-chip electrostatic discharge (ESD) protection circuits had been built in IC chips to protect the devices and circuits against ESD damage. But, ESD protection circuits constructed with the scaled-down CMOS devices are very weak to ESD stress. Therefore, novel ESD protection solutions must be developed to overcome this reliability challenge for integrated circuits fabricated in the na...
The pin-to-pin electrostatic discharge (ESD) stress was one of the most critical ESD events for differential input pads. The pin-to-pin ESD issue for a differential low-noise amplifier (LNA) was studied in this work. A new ESD protection scheme for differential input pads, which was realized with cross-coupled siliconcontrolled rectifier (SCR), was proposed to protect the differential LNA. The ...
