To identify the divider circuit configuration, we typically look for an operational amplifier (op-amp) circuit designed to output a voltage proportional to the division of two input voltages (V1V_1 and V2V_2).


Divider Circuit Configuration:

The divider circuit using an op-amp is implemented with the following key points:

  1. Configuration: It employs a feedback configuration with a multiplier circuit (often using a transconductance amplifier or resistor network) to achieve division.
  2. Output Expression: Vout=V1V2V_{\text{out}} = \frac{V_1}{V_2} where:
    • V1V_1 is the numerator input voltage.
    • V2V_2 is the denominator input voltage.
  3. Components:
    • Two input voltages (V1V_1, V2V_2).
    • Resistors and/or a multiplier circuit.
    • An op-amp with negative feedback to stabilize the operation.

Common Applications:

  • Signal processing where division of signals is required.
  • Feedback control systems to normalize outputs.
