Synthesis of compact planar inductors in LTCC technology

A simple bisection algorithm for the synthesis of compact planar inductors in LTCC technology is presented in this work. It is based on a set of heuristic rules obtained from the study of the electromagnetic behavior of these planar devices. By using a bisection method, the number of iterations is kept moderately low. In order to speed up analysis at each step, a fast planar electromagnetic solver is used which is based, once again, on the knowledge of the synthesized component. The algorithm is applied to the development of an inductor library for a LTCC process technology which last few minutes on a single CPU node.
