There are four basic feedback topologies. They are

1) Voltage-Series

2) Voltage -Shunt

3) Current- Series

4) Current-Shunt.

But wait, it doesn't stop there. Many textbooks use different nomenclature. So let's see how to get the respective synonyms for the above topologies.

The feedback topologies are also called by the following names.

1) Voltage-Series(Series-Shunt)

2) Voltage -Shunt(Shunt-Shunt)

3) Current- Series(Series-Series)

4) Current-Shunt. (Shunt-Series).

1) Feedback topology of Non Inverting Amplifer.

Here the feedback signal is derived from Voltage(

1) Voltage-Series

2) Voltage -Shunt

3) Current- Series

4) Current-Shunt.

**Identify the feedback of Amplifiers.**1) Feedback topology of Non Inverting Amplifer.

Here the feedback signal is derived from Voltage(

**Voltage**driven). The feedback signal is applied as voltage(**Series**) at the input Hence the feedback topology is**Voltage -Series or Series-Shunt.****2) Feedback topology of Inverting Amplifier**

Here the feedback signal is derived from Voltage(

**Voltage**driven). The feedback signal is applied as
Current(

**Shunt**). Hence the feedback topology is**Voltage -Shunt or Shunt -Shunt.**

**Note :**

**Non-inverting Amplifier uses Voltage Series topology**

**Inverting Amplifier uses Voltage Shunt topology**
