why there is a need to electromagnetic simulation in RFIC?
so if you have some presentations or some article please share them with us.
due to parasitic capacitores and inductres that express in post simulation.
please find uploaded files to more information.
please see books or seminars about Layout in CMOS and VLSI.
bye.
HI, helio1972:
I hope my comments are useful for you.
For any given planar circuits, there is no analytical soluton. Even for a simple stripline structure which involves one substrate, two ground planes and one strip located at the center, many people may think there is an analytical solution for it. However, considering the loss in the strip and the ground planes, such a simplest case doesn't have an analytical soluton. For single layer substrate structure such a microstrip structure, people have developed accurate analytical formulas and they are implemented into many microwave circuit simulators. Normally, those formulas can yield reasonably accurate results unless strongly coupling and 3D structures are involved. When loss is big, those formulas will become less accurate.
For RFIC structures, there are normally multiple layers of dielectrics. Some of the layers are SI layers and they are lossy. Also, the metallic loss is quite significantly. For such a situation, we normally need to use EM simulators (full-wave solvers or even quasi-static field solvers) to solve them.
Regards.
thanks jian, what you said is correct, but I need some documetns or some presentations that talk about this topic.
