Abstract :
The electrical behavior of circular spiral inductive components in a homogeneous environment is analyzed by using the concentric ring approximation. This work is based on the partial element equivalent circuit (PEEC) modeling method which is extended to rotational symmetry case. Analytic approximations of all integral formulas are used in order to enable fast computation of the partial inductance and capacitance coefficients, to provide an efficient tool for design. The result is a full modeling method allowing the plotting of complex impedance frequency response and also the drawing of charge and current densities distribution inside of the conductors.
