Abstract :
A closed form linear electrothermal model for the PIN diode showing it frequency and temperature behavior is presented. The model uses PIN diode electrical parameters such as DC forward current, I-region thickness and the temperature-dependent mobility and carrier lifetime as parameters. Impedance behavior is shown over frequency and temperature as examples of the mathematical model and the model is verified with experimental. Good agreement is seen between the model and measured data. The results show that the forward bias impedance is strongly dependent on the carrier lifetime temperature coefficient that has been shown to be a function of diode cross-section and surface passivation.
