A generic CAD model for arbitrarily shaped and multi-layer integrated inductors on silicon substrates

Abstract

A genetic and process-independent lumped element model for simulating the performance of arbitrarily shaped and multi-layer inductors on silicon substrates is presented. Integrated inductors are modeled using an equivalent two-port network for each segment of the spiral. An algorithm that extracts the complete circuit is presented in detail. Element value calculation is based on microstrip line properties, considering magnetic and
