Question

The condition for a Non-inverting amplifying circuit to operate in linear region operation  _____________

(a) (Rs+Rf)/Rs < │VCC/vg│

(b) (Rs+Rf)/Rs ≠ │VCC/vg│

(c) (Rs+Rf)/Rs > │VCC/vg│

(d) (Rs+Rf)/Rs = │VCC/vg│

I got this question in quiz.

The above asked question is from The Inverting and Non-Inverting Amplifier Circuit in section The Operational Amplifier of Electric Circuits

Answer 1

Right answer is (a) (Rs+Rf)/Rs < │VCC/vg│

To explain: Assume that opamp is ideal. The condition for the linear region operation in a Non-inverting amplifying circuit is (Rs+Rf)/Rs <│VCC/vg│.
