Intro[edit]

A network consist of three resistors connected like a π

Analysis[edit]

Formula[edit]

Choosing Resistance's Value[edit]

  • 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
