Abstract :
A new method of enforcing the bounded realness of S parameter macro-model is proposed in this paper. With a given stable rational function obtained from fitting the original data, its closest bounded real rational function is solved through semidefinite programming. This optimization problem is formulated through trace parameterization and uses minimal number of variables.
