1. The simulation principle diagram is shown in the figure:
2. Signal source parameters:
3. Capacitance parameters, including ESR and ESL.
4. The execution parameters are .ac dec 1000 1 1000Meg, frequency sweep mode.
5. Start the simulation, and then set the curve as shown in the figure below. Divide the capacitor voltage by the capacitor current to obtain the impedance frequency characteristic curve.
6. Obtain the impedance frequency characteristic curve of the capacitor:
7. The curves of multiple capacitors simulated at the same time are as follows.
