    • Determine the compliance, maximum load power, efficiency and required device ratings for class B circuits.
    • Discuss the advantages and disadvantages of class B operation versus class A operation.
    • Discuss the origin of notch distortion and methods used to mitigate it.
    • Explain the operation of a current mirror.
    • Explain the operation of a Sziklai pair.
    • Explain the operation and use of a \(V_{BE}\) multiplier.
    • Outline the operation of fully complimentary and quasi complimentary output stages utilizing direct coupled driver stages.
