New design of second order microwave integrator

New design of a second order microwave integrator is obtained by applying the evolutionary based optimization techniques in Z-domain. The structure of proposed integrator consists of eight serial transmission lines in cascade configuration. The beauty of the proposed integrator is that it has not more than 12.05% relative error over the frequency range of 1.5 GHz to 5.5 GHz. Simulation is carried out in the ADS environment, and the results are found to be in good agreement with MATAB based theoretical results.
