Question:
For the shunt-shunt feedback amplifier of Fig. 8.15a, take RF =100 kΩ and RL = 15 kΩ. For the op amp, assume that Ri =500 kΩ, Ro = 200, and av = 75,000. Calculate input resistance, output resistance, loop transmission, and closed-loop gain:
(a) Using the formulas from two-port analysis.
(b) Using the formulas from return-ratio analysis.
