Question: For the noninverting amplifier shown in Fig. 8.59, R 1 = 1 kÎ©, and R 2 = 5 kÎ©. For the op amp, take R

For the noninverting amplifier shown in Fig. 8.59, R₁= 1 kÎ©, and R₂= 5 kÎ©. For the op amp, take R_i= 1 MÎ©, R_o= 100 Î©, and a_v= 1 Ã— 10⁴. Calculate input resistance, output resistance, loop transmission, and closed-loop gain:

(a) Using the formulas from two-port analysis (Section 8.5).

(b) Using the formulas from return-ratio analysis (Section 8.8).
