The impedance model represents a series
connection of a resistor and either an inductor or capacitor.
The linear impedance connects the complex voltage
v with the complex current
i by i*Z = v.
The impedance Z_ref = R_ref + j*X_ref is given as
complex input signal, representing the resistive and reactive
component of the input impedance. The resistive component is
modeled temperature dependent, so the real part R_actual =
real(Z) is determined from the actual operating
temperature and the reference input resistance
real(Z_ref). The reactive component X_actual =
imag(Z) is equal to imag(Z_ref) if
frequencyDependent = false. Frequency dependency is
considered by frequencyDependent = true,
distinguishing two cases:
imag(Z_ref) > 0: inductive caseX_actual is proportional to
f/f_refimag(Z_ref) < 0: capacitive caseX_actual is proportional to
f_ref/fA zero crossing of the real or imaginary part of the impedance
signal Z_ref could cause singularities due to the
actual structure of the connected network.
