Q4. a) With the aid of sketches, explain the concepts of the negative and positive feedback. b) Figure 4 shows a non-inverting amplifier, which can be viewed as an open- loop op-amp connected to a feedback network. Identify the type of feedback connection of Figure 4 and show the reason. Given that R₁ = 20 kn, R₂ = 380 kn, and the open-loop gain of the op-amp in Figure 4 is A, = 10000, determine the closed loop gain, A+ = vo/v₂, of this feedback amplifier.
