Abstract :
The self- and mutual inductance of a spiral will change significantly with an increase in frequency due to the current redistribution on the metal trace. This phenomenon comes from the skin effect and the simultaneous eddy current. The basic formulae for inductance calculation are thus studied and further improved in this paper. Theories are tested with measured data on sample inductors fabricated on silicon substrate.
