Physical Modeling of GaAs MESFET's in an Integrated CAD Environment: From Device Technology to Microwave Circuit Performance

A CAD environment leading from technology to performance evaluation by integrating process, device, and circuit simulation would be a valuable tool for the development of monolithic microwave circuits. The paper focuses on the linkage between a physical device simulator for smalland large-signal characterization, and CAD tools for both linear and nonlinear circuit analysis and design. Efficient...

Numerical Simulation of Microwave GaAs MESFETs

A comprehensive physical model is used in a twodimensional numerical simulation of highly doped gallium arsenide MESFETs. Particular attention is paid to the formulation of the numerical schemes and boundary conditions to ensure accurate modelling. A specially formulated current continuity finite difference equation is used, which produces stable, accurate and efficient solutions, even at carri...

Microwave performance of optically controlled MESFETs

This paper presents the characterization of illuminated high-frequency active devices using a time domain physical simulation model. The model is based on Boltztnann’s Transport Equation (BTE), which accurately accounts for carrier transport in microwave and millimeter wave devices with sub-micrometer gate lengths. Illumination effects are accommodated in the model to represent camer density ch...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
