| Abstract: | In this paper,constant current source differential amplifier circuit is analyzed based on Multisim.With virtual instruments including voltmeters,ammeters,scilloscopes,and function generators,the paper describes the working characteristics of constant current source differential amplifier circuit.Furthermore,the virtual instruments and analytic methods in Multisim are demonstrated.The simulation results for the quiescent point and differential mode voltage amplification factor are in agreement with theoretical calculations. |
