Abstract :
The authors describe the extension of the state space technique to analysis of nonlinear and time-variant lumped/distributed (L/D) networks. The topological formulation of state, output, and nonlinear equations for nonlinear and time-variant networks containing multiports and independent sources is used. These equations have been incorporated into a computer-aided procedure for the analysis of L/D networks. The procedure can be used for the simulation of any nonlinear microwave circuit and offers the facility of developing a multiport equivalent circuit for any linear or nonlinear device or subcircuit. Several examples are successfully analyzed using the developed general program. Practical microstrip circuits of the above-mentioned nonlinear circuit are given, and experimental and simulated results show very good agreement
