X. Montagner et al., DOSE-RATE AND IRRADIATION TEMPERATURE-DEPENDENCE OF BJT SPICE MODEL RAD-PARAMETERS, IEEE transactions on nuclear science, 45(3), 1998, pp. 1431-1437
A method to predict low dose rate degradation of bipolar transistors u
sing high dose-rate, high temperature irradiation is evaluated, based
on an analysis of four new rad-parameters that are introduced in the B
JT SPICE model. This improved BJT model describes the radiation-induce
d excess base current with great accuracy. The low-level values of the
rad-parameters are good tools for evaluating the proposed high-temper
ature test method because of their high sensitivity to radiation-induc
ed degradation.
