68.1.5. Output Voltage Calculation

Try these first

1. 1.

   What is the value of beta (β) for two different transistors in this example?

   Hint

   Check the various parameters listed.

2. 2.

   What is the typical value of V_BE(on) for silicon transistors?

   Hint

   This value is standard for most silicon BJTs.

3. 3.

   What is the typical output voltage when both transistors are at 6V?

   • 4V
   • 6V
   • 8V

   Hint

   Think about the circuit's supply arrangement.

4. 4.

   True or False: Early voltage is not important in output calculations.

   • True
   • False

   Hint

   Recall the role of early voltage in amplifier performance.

5. 5.

   Design an amplifier circuit that incorporates active loads to achieve a target gain of 15. Detail your component selections and calculations.

   Hint

   Remember the interaction of collector current with voltage gain.

6. 6.

   Analyze the impact of varying early voltage on the output voltage range and explain why certain values lead to distortion.

   Hint

   Consider both theoretical and practical implications on output swing and gain.
