Modeling

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.
