Since the parasitic inductance of the planes is very low, they behave as an effective capacitance
, even at higher frequencies.
The sum of the capacitances of C1 and C3 needs to be designed high enough to keep the output voltage ripple at low levels, while considering that the effective capacitance
of the 450 V ceramic capacitors operating at 200 V is about the half of the nominal capacitance at zero DC bias voltage.
To discriminate raw and ripe mango fruits, they measured bulk impedance by LCR meter and expressed in terms of effective resistance and effective capacitance
in the frequency range of 1 to 200 KHz.
To find the effective capacitance
of the LED, the ripple current is given by
Based on the measured S-parameters, the effective capacitance
[C.sub.eff] of the capacitor can be extracted.
(8)), the effective capacitance
of the element embedded in the SRR loop is increased.
Then, considering only the solution resistance [R.sub.s], which is much lower than other resistances, and by using Brug's approach, the effective capacitance
[C.sub.B] can be calculated as (30,31,33)
This is due to the fact that the reactance produced by the effective capacitance
Co at power frequency is [10.sup.7] / [10.sup.8] Ohms.

and drive current for tunnel FET (TFET) CV/I estimation," IEEE Transactions on Electron Devices, vol.
As shown in Figure 4(b), the parasitic inductors [L.sub.C,p1] or L[C.sub.p2] will affect the effective capacitance
Larger, effective capacitance
values are expected for 2.5-micron thin-film; however, the dielectric loss increased slightly for the thin-film compared to the thick film.
