1. Explain how it is possible to identify the different current transport mechanisms that dominate the total current flowing through the pn junction. Why is this information is important to device engineers?
2. From a simple pn junction diode, predict the expected relative magnitudes of ac capacitances in a bipolar junction transistor under normal operating conditions(base emitter junction forward biased and base collector junction reverse biased).
Discuss the base emitter capacitance and base collector capacitance
