We introduce three useful impedance matching methods to help readers catch the core idea and techniques of impedance matching. Impedance matching is indispensable in high frequency circuit design, which is widely used to avoid reflection and achieve maximum power transfer. We provide abundant examples of Smith chart with details in various applications to help readers learn how to apply Smith chart in different cases.
We introduce the motivation of Smith chart in a heuristic way, and show how to build it step by step, so that readers can have an insightful understanding of Smith chart. Smith chart is the most fundamental and important tool in high frequency circuit design.
