Patterned Ground Shields For Silicon RFICs Part 3: Which Way Does The Current Really Go?
2013-11-18 09:33:36| rfglobalnet Home Page
Everything is so confusing. In Part I of this series, we found that there is something really strange about the current flowing in an Si substrate underneath a spiral inductor. It is flowing perpendicular to the direction of the spiral turns, when we thought it should be flowing parallel to the turns. This is part of a series of guest columns by Dr. James C. Rautio of Sonnet Software, Inc.

12.12: David Shields
2013-10-17 00:35:31| Powells Books Events Calendar
Blending confessional criticism and cultural autobiography, David Shields explores the power of literature to make life survivable, maybe even endurable. Evoking his deeply divided personality, his character flaws, his woes, his serious despair, he wants "literature to assuage human loneliness, but nothing can assuage human loneliness. Literature doesn't lie about this — which is what makes it essential." How Literature Saved My Life (Vintage) is a captivating, thought-provoking, utterly original book about the essential acts of reading and writing.

Patterned Ground Shields For Silicon RFICs Part 2: What Universe Are We In?
2013-05-29 12:56:26| rfglobalnet News Articles
In Part I, we used Sonnet® to investigate the current in the surface of the silicon substrate that is induced by a spiral inductor. Since it is an inductor, we were expecting the substrate current to be induced magnetically. After all, inductors are just little magnets, and we would expect inductively induced current in any nearby conductor. The silicon substrate is a conductor, kind of, right? In addition, the magnetically induced current should flow parallel to (and in the opposite direction of) the current in the spiral inductor. This behavior obeys a special case of Clerk Maxwell’s equations known as Lenz’s Law. This is all, to use American slang, a “slam-dunk”1, hardly even worth checking.
