Automatic synthesis of lossless matching networks
2010
An evolutionary method for the synthesis of impedance matching networks is proposed. The algorithm uses a coding scheme based on the graph adjacency matrix to represent the topology and component values of the circuit. In order to generate realistic solutions the sensitivities of the network parameters are accounted for during the synthesis process. To this end a closed form expression for the Transducer Power Gain sensitivity with respect to the component values of LC lossless matching networks is derived, in such a way that the effects of the components tolerance on the matching network performance can easily be quantified. The evolutionary algorithm efficiency is tested in the synthesis of an impedance matching network and the results are compared with other methods found in the literature.
