Analysis, simulation, and applications of passive devices on conductive substrates

摘要: The wireless communication revolution has spawned a revival of interest in the design and optimization radio transceivers. Passive elements such as inductors, capacitors, transformers have potential to improve performance key RF building blocks. Their use, though, not only necessitates proper modeling electrostatic magnetostatic effects, but also electromagnetic parasitic substrate coupling. This work focuses on analysis application passive devices. From Maxwell's equations, an accurate efficient technique is developed model device over wide frequency range. In particular, we demonstrate techniques for calculating loss when devices are fabricated vicinity conductive substrates silicon. Energy couples through several mechanisms, electrically induced displacement currents, by magnetically eddy currents. Green functions Poisson's equation current partial differential equations derived employed account various mechanisms. Numerical efficiently accurately compute underlying functions.
