Find the output current in the voltage series feedback amplifier.
(a) io ={ [Vo+(A*Vid)]/Ro}
(b) io ={ [Vo-(A*Vid)]/Ro}
(c) io =(Vo/Ro)*A
(d) io =[A*(Vo-Vid)]/Ro
I had been asked this question in quiz.
Question is from Voltage Series Feedback Amplifier in chapter Operational Amplifier Characteristics of Linear Integrated Circuits
