LTCC spiral inductor modeling, synthesis, and optimization

In RF/microwave circuit design, inductor design is one of the most difficult and time-consuming tasks due to the tedious trial-and-error optimization process to achieve the target specifications. This paper brings forward a fast and accurate spiral inductor synthesis method, which automatically generates physical layout of inductors according to electrical specifications. This method is based on the fusion of substrate-aware PEEC model with optimal nonlinear optimization engine. Calculated inductance and Q values show good agreement with industrial field solver and measurement results.
