PCB Impedance Design
1.What is impedance? In electrical engineering, the resistance to the current in a circuit is often called impedance. The unit of impedance is ohm, usually represented by Z, which is a complex number: Z= R i( ωL–1/(ωC)) Specifically, impedance can be divided into two parts, resistance (real part) and reactance (imaginary part). Among them, reactance…
