 In which of the following options is the expression VA / Vin given correctly in the circuit given in Figure;5 th option : NONE OF THE ABOVE

### Understanding Current Feedback Operational Amplifier (CFOA) Configurations #### Transcription of Text and Explanation 1) \(s C R_1 R_2 + 1\) 2) \(1 + s C R_2\) 3) \(1 + \frac{1}{s 2 C R_2}\) 4) \(1 + \frac{1}{s C R_1}\) #### Detailed Description of the Diagram Below the equations is a circuit diagram featuring a Current Feedback Operational Amplifier (CFOA) with several components connected to it. Here’s a detailed explanation of the diagram: - **Voltage and Current Inputs**: - \(V_{in}\): This is the input voltage applied to the circuit. - \(I_{in}\): This is the current associated with the input voltage. - **Components and Connections**: - **Resistor \(R_1\)**: Connected between point A and output terminal W of the CFOA. - **Resistor \(R_2\)**: Connected between the ground and point X at the input terminal of the CFOA. - **Capacitor \(C\)**: Connected between point Z and point X. - **Operational Amplifier (CFOA+)**: - Terminals are labeled X, Y, Z, and W. - Points W and Y are interfaced with external resistors/circuit elements. - **Connections**: - **Y Terminal**: Connected to \(I_{in}\) and \(V_{in}\). - **X Terminal**: Connected to one terminal of \(R_2\) and capacitor \(C\). - **Z Terminal**: Connected to the other terminal of capacitor \(C\) and internally to point W. - **W Terminal**: Connected to \(R_1\) and to point A. This configuration is typical in analog signal processing, where the behavior of the circuit can be analyzed using the given mathematical expressions to understand how the components influence the system’s overall response. The use of resistors and capacitors enables the manipulation of frequency responses, making this setup versatile for filters, oscillators, and other applications in electronic design.
