A] Find the gain of this non- inverting amplifier B] What are the appropriate values for R1 and R2 to convert this amplifier into a voltage follower, and why? R1 100 R2 110 Solution A) The gain of the opamp = Vo/Vin = 1+(Rf/R1) = 1+(10k/1k) = 11 B) The non inverting amplifier will act as Voltage follower when R1 = Rf =0 then Vo/Vin = 1+0 = 1 or Vo = Vin.
