[edit | edit source]Choosing Resistance's Value
[edit | edit source]- 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 | edit source]This network can be used as Voltage Amplifier, Voltage Follower, Voltage Attenuator by choosing the right value for the resistors
