A more accurate procedure can be followed considering that the reported curves can be
represented by the following equation (f in kHz and R in k
Ω):
Equation 40
In particular the constant, k, and the exponent, e, can be calculated for a given Cosc
(expressed in pF) as follows:
Equation 41
Equation 42
Firstly k and e should be found and then R can be calculated as follows:
