این پایان نامه ، شامل طراحی و شبیه سازی یک pll ، با توان مصرفی کم و jitter پائین در رنج فرکانسی 1ghz-2ghz ، در تکنولوژی cmos,0/35um می باشد.به منظور بدست آوردن فرکانس بالا و توان مصرفی کم ، یک اسیلاتورحلقوی با دو delay stage معرفی می شود.ساختار دیفرانسیلی این اسیلاتور موجب کاهش نویز تغذیه تزریق شده به مدار می گردد. علاوه بر آن بخاطر swing ولتاژ بالا، phase noise در م...
Light scalars (as the axion) with mass m ~ 10^{-22} eV forming a Bose-Einstein condensate (BEC) exhibit Jeans length in kpc scale and were therefore proposed as dark matter (DM) candidates. Our treatment here is generic, independent of particle physics model applies to all DM BEC, or out equilibrium. Two observed quantities crucially constrain an inescapable way: average density rho_{DM} phase-...
urban design problems have become so complex that no single designer is able to consider all aspects of a design area simultaneously. lately the application of computerized and scientific methods have helped designers analyze complex problems. one of these new methods is space syntax. the purpose of this study is to first investigate the strengths and weaknesses of this method and then suggest ...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
