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.
Silicon Diodes eliminate need for snubber capacitors.

Available from 10–40 A in common-cathode configuration, 200 V Qspeed™ LQA200 Series is based on merged-PIN technology that offers soft switching and low reverse recovery charge. Balance of features permits use of small magnetic components while maximizing operational efficiency. Available in DPAK, D2PAK, and TO-220 packages, diodes are suitable for use in power-supply output rectification circuits for hard- or soft-switching applications such as telecom power supplies and audio amplifiers.
