Efficient simulation and optimization of linear active networks

Abstract

An efficient method for the optimization of linear networks is presented. The computation cost in circuit optimization mainly depends on the simulation of network; in general, the simulation of a linear network needs to solve a high dimension linear algebra equation. An important characteristic in circuit optimization is that the number of independently tunable parameters is small. In terms of the property of linear networks, the circuit is described by a multiport network in the presented method, and the hybrid matrix is established. The dimension of the equation to be solved in the same as the number of optimization parameters in objective function evaluations which provides a fast simulation tool for optimization.
