Figure P5.34 shows the diagram of an inverting operational amplifier.

a. Assuming an ideal operational amplifier, use a similar procedure to the one outlined in Problem 52 to find the system equations.

b. Draw a corresponding block diagram and obtain the transfer function V_o(s)/V_i(s).

c. Show that when A → ∞; V_o(s)/V_i(s) = -R_f/R_i.

Data From Problem 52:

Figure P5.33 shows a noninverting operational amplifier.

Assuming the operational amplifier is ideal,

a. Verify that the system can be described by the following two equations:

b. Check that these equations can be described by the block diagram of Figure P5.33(b).

c. Use Mason’s rule to obtain the closed-loop system transfer function V_o(s)/V_i(s).

d. Show that when A → ∞; V_o(s)/V_i(s) = 1 + R_f/R_i.
