Hi there,It's simple, feedback and "closed loop" Gain (after feedback is applied) are inversely proprtional.
That means that as the amount of negative feedback goes up, the gain goes down and reverse, reducing negative feedback increases gain.
Essntially, negative ffedback improves the aparent linearity of a circuit while reducing it's gain. Hence you need excess gain to start with in order to be able to use negative feedback.
