Feedback amplifiers improve stability and reduce distortion using negative feedback.
Power amplifiers deliver large amounts of current and voltage to loads such as loudspeakers.
Tuned amplifiers use LC circuits to amplify specific frequencies, ideal for RF and communication systems.
Op-Amps have high gain and input impedance, and are used in amplification, integration, and filtering.
Current transformers are not op-amp applications; Op-Amps are used for analog signal processing.
Tuned amplifiers are used for selecting and amplifying signals in a narrow high-frequency band.
Class A amplifiers are linear but inefficient, making them ideal for audio where distortion must be minimal.
The voltage follower configuration of an op-amp provides unity gain and is ideal for impedance matching.
