A circuit using op-amp shown below has Correct Answer Voltage shunt feedback

Concept-

Identification of Feedback topology-

1. Identify the feedback network/element.

2. If at the output side, feedback is connected to the output of the circuit directly, name it as 'voltage sampling', or else 'current sampling'

3. If at the input side, feedback is connected to the input given to the circuit directly, name it as 'shunt mixing ' or else 'series mixing'

Analysis:

Step-1: feedback element is both R1­ Resistor

Step – 2: The feedback element is directly connected to output so voltage sampling.

Step – 3: The feedback element is directly connected to input so shunt mixing.

Hence, Voltage-shunt is the right answer.
