Input impedance of thin film resistor¶

Thin-film resistors in integrated design are used in microwave circuits. The input impedance of a thin-film resistor depends on its resistance and capacitance, as well as on the angular frequency.

input_impedance¶: Input electrical_impedance of the resistor.

Symbol:: Z
Latex:: \(Z\)
Dimension:: impedance

resistance¶: electrical_resistance of the film.

Symbol:: R
Latex:: \(R\)
Dimension:: impedance

angular_frequency¶: angular_frequency of the current.

Symbol:: w
Latex:: \(\omega\)
Dimension:: angle/time

capacitance¶: capacitance of the film.

Symbol:: C
Latex:: \(C\)
Dimension:: capacitance

law¶

Z = R / (1 + I * w * R * C / 3)

Latex:: \[Z = \frac{R}{1 + \frac{i \omega R C}{3}}\]
