Describe the motion of electrons and holes in a p-n-p bipolar transistor biased in the forward active mode with VBC = 0. How will it change if reverse bias is applied to the B-C junction? How much voltage should be applied to the E-B junction? Suggestion: Use the BJT energy band diagram. 2. Design a p-n-p BJT with current gain 150. 3. How does recombination in the quasi-neutral base region affect the emitter, base and collector current? 4. What is the Early effect and how does it affect the transistor I-V characteristics? 5. What is the Webster effect?
