SUMMARY

The discussion centers on the configuration of a voltage follower using an operational amplifier (op-amp) with a resistor ratio of 9:1. In this setup, the two resistors are positioned in a feedback loop, where one resistor connects the output to the inverting input, and the other connects the inverting input to ground. The closed-loop gain for this configuration is calculated using the formula Vout = Vin * (R2 / (R1 + R2)), where R1 and R2 represent the resistors in the feedback loop.

PREREQUISITES
  • Understanding of operational amplifier configurations

Op-Amp: "voltage-follower" question

Hi all, ...

If a simple op-amp circuit is described as:
-> being in a "voltage-follower with-gain" configuration, and
-> having a resistor ratio of 9:1

...Where are the two resistors positioned with respect to the op-amp circuit element, and
...How, if at all, doe they come into play when calculating the configuration's "closed-loop gain"?

Thanks heaps!
