| Abstract: | As a kind of powerful EDA simulation software,Multisim offers a lot of convenience functions,but it can not directly be used in phase difference measurement of the sinusoidal steady state circuit and so on.In order to solve this problem,a new circuit is designed to measure the phase difference,which is composed of the amplifiers and the software tools.The circuit constituent and the work principle are introduced,the simulation of the design circuit and the living example show further the method of measurement,and we analysis the error of the related parameters in detail,the result indicates that the phase deference measurement circuit with broad frequency range and high precision can measure the phase deference directly. |
