How to place inductance on printed circuit board of switching regulator

Switching regulators for voltage conversion usually use inductors to store energy temporarily. These inductors are usually very large in size and must be positioned in the printed circuit board (PCB) layout of switching regulators. This task is not difficult because the current through the inductor may change, but not instantaneously. It may be continuous and [...]

Introduction to impedance matching knowledge

Impedance matching is a part of microwave electronics. It is mainly used in transmission lines to achieve the purpose that all high-frequency microwave signals can be transmitted to the load point, and no signal will be reflected back to the source point, so as to improve energy efficiency. In general, there are two kinds of [...]
