These are positive or regenerative feedback and negative or degenerative feedback (Ellinger, 2008). The difference between two kinds of feedback entails whether the feedback signal is out of phase or in phase with an input signal. The term feedback can also refer to the process through which information on future or present events tend to affect similar events in future while a feedback amplifier is that which the fraction of output energy gets fed back to an input of that same circuit. As widely cited, there are two types of feedback. These are negative also referred to as inverse or degenerative information, and the positive also referred to as direct or regenerative feedback. The difference between the two types of feedback is basically on whether the feedback signal is out of phase or in phase with an input signal.
Negative feedback refers to the feedback signal that is 180 degrees out of phase concerning that of the input signal. Generally, negative feedback can be divided into two: voltage feedback and current feedback. . As often is the case, the recent feedback is applied purposely to reduce the input amplifier. . However, there are cases where both feedbacks may exist in a circuit. In such a case, both current voltages would be feedback towards the input in parallel or series. This, therefore, imply that the information would be represented as series-voltage feedback, series-current feedback, shunt current feedback, and shunt- voltage feedback. Arguably, negative feedback makes again in a circuit to be stable. Mathematically, it can be shown that A1= AB + A/1.  . . .
For cases where AB>.>. one, the expression reduces to A1=1/B. The mathematical word implies that such a circuit is entirely independent of the internal gain.
It is worth noting that the negative feedback it has many merits.  .It has been cited as being the best in creating the practical circuits due to its characteristic nature of being able to set rates, gains, alongside other significant parameters. Moreover, negative feedback can make courses self-correcting and stable. By and large, the fundamental principle of the negative feedback is such that the output drives in such a direction creating an equilibrium condition. For an op-amp circuit without a feedback, there is lacking a corrective mechanism.
