Feedback connection types

• Voltage series feedback

• Voltage shunt feedback

• Current series feedback

• Current shunt feedback

Ø Here voltage refers to small part of voltage as input to the feedback network

Ø Current refers to tapping some part of output current through feedback

network.

Ø Series refers to connecting feedback signal in series with the input signal

voltage.

Ø Shunt refers to connecting feedback signal in shunt with the input signal

voltage

Ø Series feedback connections increases the input resistance

Ø Shunt feedback connections decreases the input resistance.
