The document discusses feedback in operational amplifiers (op-amps) and some of their applications. It explains that negative feedback occurs when some of the op-amp's output is fed back to its inverting input, which produces a more stable and better output. It then describes op-amp applications such as the summing amplifier, differentiator, and integrator. Finally, it mentions some real-world uses of op-amps like in ECGs, strain gauges, and piezoelectric transducers.

4. WHAT IS FEEDBACK AND NEGATIVE FEEDBACK
IN OP-AMP?
• FEEDBACK IS A PROCESS IN WHICH SOME
PORTION OF OUTPUT OF OP-AMP IS FED BACK
AGAIN TO IT’S INPUT.
• IN NEGATIVE FEEDBACK OF OP-AMP, THE
OUPUT OF OP-AMP IS FED BACK TO THE
INVERTING INPUT OF OP-AMP.
• Why Negative feedback? NEGATIVE FEEDBACK
PRODUCE BETTER AND STABILIZED OUTPUT IN
AN OP-AMP.
