Keywords:Voltage Series Negative Feedback Amplifier, Proteus 8 Professional Software, Common-Emitter Amplifier
In this paper, the common two-stage amplifier voltage series negative feedback amplifier circuit is analyzed theoretically. With negative feedback, the closed-loop voltage gain can be reduced and controlled so that the op-amp can function as a linear amplifier. Negative feedback is the basic method and essential means of improving amplifying circuit efficiency. Then using Proteus 8 professional as simulation software, the relationship between the gain obtained by open-loop and the simulation of the closed-loop and the pass-band is shown by comparing the real experimental data with the result of the circuit’s simulation and the waveform. Negative feedback opposes or subtracts from the input signals giving it many advantages in the design and stabilization of control systems. Basically the relationship consistent with the calculated results, that is in good agreement with the theoretical analysis.
