Positive Feedback: Enhances the original signal, resulting in amplification or oscillation.
Negative Feedback: Reduces the original signal, promoting stability and reducing distortion.

Operational Amplifiers: The Versatile Workhorses

Op amps are ubiquitous in electronic circuits, renowned for their versatility and wide range of applications. These integrated circuits amplify signals, perform mathematical operations, and act as comparators or voltage followers. Their high input impedance, low output impedance, and high gain make them indispensable in various electronic designs.

Inverting Configuration: Inverts the input signal, creating a negative feedback loop.
Non-Inverting Configuration: Maintains the input signal's polarity, providing a positive feedback loop.
