An amplifier with a nominal gain 1000 V/V exhibits a gain change of 10% as the operating temperature changes from 25 C to 75C. If feedback with a feedback factor B=0.1 is used, what is the new gain and the percentage change in gain? How you do you compensate for the lost gain. What should be the minimum value of feedback factor if it is required to restrict the change in gain to less than 1%?

. An amplifier with a nominal gain 1000 V/V exhibits a gain change of 10% as the operating temperature changes from 25 C to 75C. If feedback with a feedback factor B=0.1 is used, what is the new gain and the percentage change in gain? How you do you compensate for the lost gain. What should be the minimum value of feedback factor ß if it is required to restrict the change in gain to less than 1%?
