The article discusses the key factors influencing the discrepancy between the experimental and model curves when simulating a p – n junction on pulsed broadband signals. The reason for the discrepancy lies in the quasi-static representation of the forward and backward reconstruction of the p – n junction in the standard SPICE model. The quasi-static approximation does not take into account the transient processes in the p – n junction, which are associated with the transit time of minority charge carriers and the series resistance of losses.
