Study Notes
Transistors
- The symbol for an NPN transistor is
- Transistors have various applications, including amplification, switching, and voltage regulation
- Biasing is required in a transistor to establish a stable operating point, allowing it to function correctly
- In a transistor, α (alpha) is the current gain in common base configuration, and β (beta) is the current gain in common emitter configuration, where β = α / (1 - α)
IC741
- The Pin diagram of IC741 is used in operational amplifiers (op-amps)
