【Abstract】 The procedure of extraction of PN diode parameters from forward I V charcteristics is studied. Differing from the usual model, the present model of PN diode consists of the effect of shunt conductance on the current. By reading out four ( V,I ) value from I V characteristics, the model equation group is numerically solved by Newton method. The PN diode parameters, such as the inverse saturation current, the series resistance, the emission factor, and the shunt conductance, could be extracted together. The computed results show that the procedure is very simple, convenient and practical.更多还原
