A voltage amplifier without feedback has a nominal gain of 500. The gain, however, varies in the range of 475 to 525 due to parameter variations. In order to reduce the per-unit change to 0.02, while maintaining the original gain of 500, if the feedback is introduced, find the new direct transfer gain G and the feedback factor H.
Q. Why CE configuration is widely used in amplifier circuits? The main ability of an transistor lies in amplifying weak signals. The transistor cannot alone perform this functi
