Class AB Amplifiers Flashcards
What distinguishes Class AB amplifiers from Class A and Class B?
Class AB amplifiers combine features of Class A and Class B amplifiers.
Where is the biasing point located in a Class AB amplifier?
The biasing point of a Class AB amplifier is slightly above the cutoff region.
What advantage does a Class AB amplifier offer in terms of distortion compared to Class B?
Class AB amplifiers have lower distortion compared to Class B due to some overlap in conduction.
What is a disadvantage of Class AB amplifiers in terms of efficiency compared to Class B?
Class AB amplifiers have lower efficiency compared to Class B amplifiers.
What is a key application of Class AB amplifiers?
Class AB amplifiers are commonly used in applications where a balance between efficiency and linearity is required, such as in audio amplification for musical instruments.
