Derivation of Non-Inverting Op-Amp, Closed loop gain, Input Impedance, Output Impedance In English

Описание: Derivation of parameters of Non Inverting Operational Amplifier

1.Feedback gain/Closed loop gain ,Af
2.Input resistance with feedback,Rif
3.Output resistance with feedback,Rof

Noninverting Operational amplifier is also called as voltage series feedback amplifier.

Voltage sampling
When V0 = 0 then Vf = 0

Series mixing
When feedback signal is series with input signal
