Further Research on the Experiment of Differential Amplifier Circuit Based on Multisim
According to the requirements of new engineering and the characteristics of higher vo-cational students,it is proposed that students use Multisim software to design the differential amplifier circuit before training.In the training,the design method of differential amplification circuit and wheth-er it meets the performance index are discussed,and the amplitude of differential mode input signal is changed.The output waveform of differential mode amplification is observed and the differential mode transmission characteristic curve is drawn.The static and dynamic parameters of differential mode and common mode input are measured.The simulation results,theoretical analysis and hardware circuit test results are consistent.Practice has proved that the introduction of Multisim software simulation enables students to carry out project driven and exploratory learning in practice,improves students'interest in learning,practical innovation ability in designing circuits and new engineering courses,and develops good professional quality.
