Transcribed Image Text:**Circuit Analysis with Ideal Op-Amps**
In the circuit below, assume the op-amps are ideal. The sinusoidal voltage source in the circuit is generating a voltage given by \( v_{in}(t) = 10\sqrt{2}\cos(100t)(V) \).
**Tasks:**
(a) Find the steady state expression for \( v_o(t) \).
(b) What would be the minimum value of \( V_{cc} \) to ensure that neither of the op-amps are saturated?
**Circuit Diagram Details:**
- The circuit has two operational amplifiers in a dual-stage configuration.
- Each op-amp is powered by a dual supply of \( +V_{cc} \) and \( -V_{cc} \).
- The input voltage source \( v_{in}(t) \) is connected to the first resistor with a resistance of 200 Ω.
- The first op-amp is connected with feedback and forward resistors of 200 Ω each.
- The second op-amp also has feedback and forward resistors of 200 Ω each.
- There is a 100 Ω resistor connected between the first and second op-amp.
- A 100 μF capacitor is connected to the output of the second op-amp creating an integrator circuit.
**Problem Solving Approach:**
1. **Steady State Expression for \( v_o(t) \):**
- Analyze the voltage gain for each op-amp using the resistor values provided.
- Consider the frequency response due to the capacitor and identify the effect on the sinusoidal input.
- Compute the overall transfer function to determine \( v_o(t) \) based on \( v_{in}(t) \).
2. **Minimum \( V_{cc} \) Value Analysis:**
- Determine the output voltage swing required for proper operation of the op-amps.
- Ensure both op-amps remain within their linear operating regions to avoid saturation.
- Calculate \( V_{cc} \) using the maximum output voltage levels determined from \( v_o(t) \).
**Note:** This analysis assumes ideal op-amps, meaning infinite input impedance, zero output impedance, and infinite gain.
