Optimize the Efficiency of Lossy Matching Network: A Top-Down Splitting Algorithm Based on Generalized Quality-Based Equation

For the lossy matching network, the efficiency of transferring the power is one of the most important factors. In this brief, a novel generalized quality-based equation has been derived which can accurately calculate the efficiency. This generalized equation covers all the situations that the source and load impedance are both complex and consider both the loss of inductor and capacitor. Meanwhile, the SPICE simulations have been carried out to validate the accuracy of the proposed equation. Based on this generalized equation, a top-down splitting algorithm is proposed to further optimize the efficiency of multi-stage matching network. The proposed method shows better improvement of efficiency than prior works.
