Problem #1
An inverting amplifier circuit is given in figure 1.
a) Assume the op amp is ideal and determine vo .
b) Replace the operational amplifier by the finite gain model shown in figure 2. Assuming the parameters of the op amp are Ri = 100kΩ, Ro = 100kΩ, and A = 100,000, repeat the analysis and find vo.
Need a hint?
Use the ideal opamp model.
