Which of the following statements is NOT correct about Bipolar Junction Transistors (BJTs)?
- 1The voltage-divider bias configuration has much less stability than the fixed bias configuration.✓
- 2The common-emitter bias configuration with an unbypassed emitter resistor has a larger input resistance than the bypassed configuration.
- 3A common-base configuration has very low input impedance.
- 4An emitter-follower configuration will always have an output voltage slightly less than the input signal.
Correct answer
The voltage-divider bias configuration has much less stability than the fixed bias configuration.
