WebOct 24, 2024 · The forward Gummel characteristics for high-dose-rate and low-dose-rate irradiation are shown in Fig. 2.23. The base currents all increase monotonically with accumulated total dose, especially in low V BE region, while collector current remains unchanged during the whole irradiation; thereby, a remarkable drop appears in the … WebApr 11, 2024 · In this experiment, you will characterize the current-voltage characteristics of an npn bipolar junction transistor (BJT) using the IIT-Kharagpur Lab-on-Demand. This experiment involves measurement of current-voltage characteristics (Gummel plot).
