Choosing Resistance's Value

  • R2 = 0
The fomula above now becomes
 
R3 > R1 , Vo > V1 . This network acts as Voltage Amplifier
R3 = R1 , Vo = V1 . This network acts as Voltage Follower
R3 < R1 , Vo < V1 . This network acts as Voltage Attenuator
  • R3 = 0
The fomula above now becomes
 
This network acts as Voltage Attenuator
  • R1 = 0
The fomula above now becomes
 
This network acts as Voltage Amplifier 1 +  

Summary

edit

This network can be used as Voltage Amplifier, Voltage Follower, Voltage Attenuator by choosing the right value for the resistors
