Question

The steady state output \( V_{\text{out}} \), of the circuit shown below, will

• A. saturate to +V\(_{DD}\)
• B. saturate to -V\(_{EE}\)
• C. become equal to 0.1 V
• D. become equal to -0.1 V

Hint:

In an op-amp circuit with negative feedback, the output voltage will saturate at the supply voltage limits when the input voltage is sufficiently high, in this case, to -V\(_{EE}\).

Answer 1

The Correct Option is B

Step 1: Understanding the circuit.
The circuit shown involves an operational amplifier (op-amp) with feedback and a resistor network. The input voltage is 0.1 V, and the op-amp will adjust the output voltage to maintain the virtual short between its inverting and non-inverting terminals. This behavior is typical of negative feedback systems in op-amp circuits. Step 2: Analyzing the behavior of the circuit.
- The op-amp will adjust the output voltage to drive the inverting terminal to 0 V (virtual ground). This will cause the output to saturate to the supply voltage levels. - In this case, given that the input is positive (0.1 V), the op-amp will try to move the output to the negative supply voltage (-V\(_{EE}\)) to maintain the virtual short. Thus, the output will saturate to the negative supply voltage.
Step 3: Conclusion.
The correct answer is (B) because the output voltage will saturate to -V\(_{EE}\) based on the negative feedback and virtual ground concept.
