Gain Bandwidth Product is constant and describes the op amp gain behavior with respect to frequency. You can extend the bandwidth (to a certain degree) but at the cost of the gain. We need to be aware of the Gain-Bandwidth Product here. Extend the bandwidth of the amplifier.Control the input and output resistances - with an appropriate feedback configuration the input and output resistances can be controlled.This interference could be external or from the circuit components themselves. Reduce the effect of noise - reduces the amount of unwanted electrical interference on the output.Reduce non-linear distortion - the output is proportional to the input.Desensitize the gain - the value of the gain becomes less sensitive to variations in the values of the circuit component, such as temperature effects on transistors.Feedback is applied to the system to affect one or more of the following properties: There are two types of feedback: positive (regenerative) and negative (degenerative). What is feedback? Feedback occurs when the output of a system is fed back into as input(s). We are going to talk about feedback and closed-loop gain and application.
We simply verified the Vout equation in the ideal op amp video to show why it is commonly referred to as a voltage-controlled voltage source. Op amps are not meant to be used as stand-alone devices.
