Due to the continuous rising demand of handheld devices like iPods, mobile, tablets;specific applications like biomedical applications like pacemakers, hearing aid machines and space applications which require stable digital systems with low power consumptions are required. As a main part in digital system the SRAM (Static Random Access Memory) should have low power consumption and stability. As we are continuously moving towards scaling for the last two decades the effect of this is process variations which have severe effect on stability, performance. Reducing the supply voltage to sub-threshold region, which helps in reducing the power consumption to an extent but side by side it raises the issue of the stability of the memory. Static Noise Margin of SRAM cell enforces great challenges to the sub threshold SRAM design. In this paper we have analyzed the cell stability of 9T SRAM Cell at various processes. The cell stability is checked at deep submicron (DSM) technology. In this paper we have analyzed the effect of temperature and supply voltage (Vdd) on the stability parameters of SRAM which is Static Noise Margin (SNM), Write Margin (WM) and Read Current. The effect has been observed at various process corners at 45 nm technology. The temperature has a significant effect on stability along with the Vdd. The Cell has been working efficiently at all process corners and has 50% more SNM from conventional 6T SRAM and 30% more WM from conventional 6T SRAM cell.

A controlled, efficient and robust process for the synthesis of an epidermal growth factor receptor inhibitor: Afatinib Dimaleate

引用

Chemical Reports 2019年第1期1卷 3-12页

作者： Pawan kumar Premnath Dhande Muhammad Taufiq F. Mazlee Suhaila M. Yaman Nurul Syazwani Nadirah Binti Muhammad Syafiq Chandran Mohd Zulfadli Bin Makhtar Dhramveer Singh Shekhawat Sunil Vasudeorao Lanke ramesh kumar Sandeep Mhetre Oncogen Pharma Sdn Bhd No.3 Jalan Jururancang U1/21 Hicom Glenmarie Industrial Park 40150 Shah Alam Selangor Malaysia.

A simple, controlled, robust and scalable three-stage manufacturing process of Afatinib Dimaleate was assessed and optimized leading to improved yield and quality. The synthetic process involves sequence of reactions as nitro-reduction, amidation and salification. The developed and optimized route was demonstrated on 300 g scale with over all isolated yield of 84% for Afatinib free base. The developed process has the capability to control not only the process related impurities but also the degradation impurities. One new impurity was identified during the process development studies and characterized as acetamide impunity, chemically known as (S)-N-(4-((3-chloro-4-fluorophenyl) amino)-7-((tetrahydrofuran-3-yl) oxy) quinazolin-6-yl) acetamide. Other impurities were identified as degradation impurities, Process impurities and were labeled as 1-(4-((3-chloro-4-fluorophenyl) amino)-7-(((S)-tetrahydrofuran-3-yl) oxy) quinazoline-6-yl)-5-Hydroxypyrrolidin- 2-one (hydroxy impurity), Afatinib N-Oxide impurity and N4-(3-chloro-4-fluorophenyl)-7-[[(3S)-tetrahydro- 3-furanyl] oxy]-4,6-quinazolinediamine (Intermediate-1).
