The following steps are the same as method one and will not be listed again.
The Challenges Faced by Electronic Circuit CAD in High-Frequency Circuit Analysis
Y(j )=({1}over{R_{O}}+{r}over{r^{2}+ ^{2}L^{2}_{O}})+j( C_{O}-{ L_{O}}over{r^{2}+ ^{2}L^{2}_{o}})
The only way to increase the self harmonic frequency SRF when the inductance L0 is at the rated value is to reduce the parasitic capacitance C0
There are many types of inductors, and the classification standards are also different. Usually classified into fixed inductors,
Distributed capacitance. The capacitance between turns of the coil, between the coil and the shielding cover (when there is a shielding cover)
