Assignment: Modern Solid State Devices- Bipolar Junction Transistors
Write 600+ words that respond to the following questions with your thoughts, ideas, and comments. Be substantive and clear, and use examples to reinforce your ideas.
BJTs (Bipolar Junction Transistors) are the back bone of analog and BiCMOS circuits. In your own words explain the structure and operation of a BJT transistor in details. Discuss if we can build a BJT transistor by connecting two diodes back to back rather than fabricating one. Why not? Also discuss the exact role of coupling and bypass capacitors for a BJT circuits. What happens if the coupling capacitors are eliminated? What is the effect of DC signal or ac signal on these capacitors?
