A New Approach to the Computer-Aided Design of Nonlinear Networks and its Application to Microwave Parametric Frequency Dividers

A new cost-effective method allowing nonlinear microwave circuits to be designed by computer is demonstrated by application to parametric frequency dividers. The method is based on frequency-domain representations of both nonlinear circuit components and network voltages and currents. A special optimization strategy determines the unknown parameters of the linear part of the circuit while estimating the need for a complete analysis of the nonlinear network at each step of the iterative process.
