Feedback Circuit
The function of the feedback circuit is to return a fraction of the output voltage to the input of the amplifier.
Feedback Circuit
The function of the feedback circuit is to
return a fraction of the output voltage to the input of the amplifier. Fig.
13.6 shows the feedback circuit of negative voltage feedback amplifier. It is
essentially a potential divider consisting of resistances R1 and R2.
The output voltage of the amplifier is fed to this potential divider which
gives the feedback voltage to the input. Referring to Fig. 13.6, it is clear
that :
