For an ideal op amp, choose R1 and R2 to get a voltage gain of -20V/V and an input resistance of 80kΩ. ### Inverting Amplifier Circuit DiagramThis diagram illustrates an inverting amplifier circuit, often used in analog electronics for signal processing.#### Components:1. **Voltage Source (Vi):** - Represented by a circle with a plus and minus sign, indicating polarity. - Provides the input voltage to the circuit.2. **Input Resistor (Rin):** - Label: Rin - Connected in series with the input voltage source. - Controls the input current to the operational amplifier.3. **Resistor (R1):** - Label: R1 - Positioned between the input voltage (Vi) and the inverting input (negative terminal) of the operational amplifier (Op-Amp).4. **Operational Amplifier (A):** - Represented by a triangle, with the point indicating the output. - The inverting input (-) receives the signal from R1. - The non-inverting input (+) is grounded.5. **Feedback Resistor (R2):** - Label: R2 - Connects from the output (Vo) of the Op-Amp back to the inverting input, creating a feedback loop.6. **Output Voltage (Vo):** - The output signal is taken from the Op-Amp's output terminal.#### Functionality:- **Inverting Amplification:** - The input signal (Vi) is inverted, and the gain is determined by the ratio of resistors R2 to R1. - The output voltage (Vo) is given by the formula: \( Vo = -\left(\frac{R2}{R1}\right) \times Vi \).This setup is commonly used in audio, instrumentation, and communication systems to amplify and invert signal voltages with precision and control.
