WebThe two basic op-amp circuit configurations are shown in Figs. 4.2 and 4.3. Both circuits use negative feedback, which means that a portion of the output signal is sent back to the negative input of the op-amp. The op-amp itself has very high gain, but relatively poor gain stability and linearity. WebMay 25, 2024 · But today negative feedback is used in all good quality amplifiers because of its several merits. Merits of Negative Feedback Increased stability of gain. Reduction in distortion and nonlinearity. Flat response over a wider frequency range. Reduction in noise generated within the amplifier.
