Why we need negative feedback?

By its very nature a DC circuit will not exhibit any form of Reactance, therefore, opposition to current flow will always be measured in Resistance.
Reactance exists in two forms, Capacitive & Inductive. Impedance can, therefore, be thought of as the opposition of electrical current flow in an AC circuit.

Hi Meda and Komal,
I have a doubt. The Gain of OPAMP is infinite. And we know that GBW product is always constant. Then how it is possible for OPAMP to have infinite bandwidth too?

Amplifier is electronics devices save output energy and give (save energy) to input energy with higher amplitude it's mean transmission energy between output energy and input (power supply).

Comparator is a device to compare two signals. A and B are two signals it compare three conditions.
i.e A>B, A<B, A = B. Depending on the values it gives output.
i.e A>B, A<B, A = B. Depending on the values it gives output.

Open loop gain is the gain of op amp without feedback. So what is comparator?
