26.6: Questions

  • Page ID
  • 1. Does the maximum load power compare favorably to the supplied DC power and the transistor’s power dissipation? That is, is the circuit efficient? How does it compare to class A operation (Exercise 12)?

    2. How is the notch distortion affected by the power supply?

    3. Compare the resistor bias and diode bias circuits regarding idle current \((I_{CQ})\) and notch distortion. Compute the \(I_{CQ}\) versus \(V_{CC}\) stability \((I_{CQ-MAX} / I_{CQ-MIN})\) of each circuit using the first and last entries of Tables 26.5.1 and 26.5.2.

    4. How does the class B circuit distortion compare to class A operation (Exercise 12)?

    5. Would increasing the Vcc supply increase the output compliance? Why/why not?
