Class A/B amplifiers are electronic devices used to amplify audio signals. They combine the features of Class A and Class B amplifiers, providing a balance between sound quality and efficiency. Class A amplifiers are known for their high fidelity but are less efficient, while Class B amplifiers are more efficient but can introduce distortion. Class A/B amplifiers aim to minimize these drawbacks. These amplifiers operate by using two output transistors, one for each half of the audio signal. During operation, each transistor conducts for half of the signal cycle, reducing power loss and heat generation. This design allows Class A/B amplifiers to deliver good sound quality while being more energy-efficient than Class A amplifiers.
