Type selection algorithm for self resonant frequency capacitors(I)

The self resonant frequency of the third capacitor is consistent with the parallel resonant frequency.

The self resonant frequency of the third capacitor is located in the middle of the other two self resonant frequencies.

Determining which algorithm to choose depends on the capacitor's ESL, ESRs, and the difference between the capacity values. Since the maximum number of types of capacitors available is uncertain, it may be possible to allow only three or fewer types of capacitors. Based on the assumption that there is no direct relationship between the maximum type and the cutoff frequency, this paper focuses on the selection algorithm of capacitance when applying four or more kinds of capacitors. The case of one capacitor, two capacitors and three capacitors are briefly discussed.
