Problem #2

An non-inverting amplifier circuit is given in figure 1.

a) If the load resistor RL = 1kΩ, determine vo assuming the op amp is ideal. Repeat the analysis for RL = 100kΩ.

b) Replace the operational amplifier by the finite gain model shown in figure 2. Assume the parameters of the op amp are Ri = 100kΩ, Ro = 100kΩ, and A = 100,000. Repeat the analysis of a).
