At low frequency, a transmission line, open at one end, looks like a capacitor. After all, it is just two conductors, the signal path and the return path, with some insulation between them. This is ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

In the latest version of its Q3D Extractor, Ansoft gives designers a window into the capacitance and conductance issues prevalent in lossy dielectrics. Version 8 of the parasitic extraction tool ...

Ferroelectrics are getting a serious re-examination, as chipmakers look for new options to maintain drive current. Ferroelectric materials can provide non-volatile memory, serving an important ...
