Solution

ANSWER:

When V₀ is zero, the given circuit is an amplifier wih negative feedback with a gain of -200k/2k = -100 V/V

V0 = -100*Vs.

At any given condition, the output voltage always has to be netween -Vcc to +Vcc. If the theoretical o/p is out of this boundary, the o/p will then saturate and remain constant at +Vcc or -Vcc.

In this case, -15 < V0 < 15

-15 < 100*Vs < 15

-0.15 < Vs < 0.15.

The range of Vs for which the amplifier is linear is -0.15 < Vs < 0.15.
