Abstract
The paper applies the block diagram for simulation analysis and theoretical calculations of parallel negative current feedback amplifier circuit which is designed by operational amplifier.The result of simulation indicates: 1) closed-loop gain and open-loop gain to meet basic relationship;2) the stability of feedback is consistent with the theory and input resistance decreased and output resistance increased;3) the feedback coefficient is approximately equal to the reciprocal of the closed-loop gain in deep negative feedback conditions,which confirmed elementary conclusions and formulations in negative-feedback amplifier.
