MultiSim Tutorial 2 Grade 9 to Engineering（电路仿真教程2 9年级工程）.pdf

Introduction to MultiSim – Part 2 Prepared by: Mohamad Eid Summer 2007 The purpose of this tutorial is to demonstrate the use of MultiSim to simulate operational amplifier circuits (uA741 OpAmp), such as inverting and non-inverting amplifiers, filters, and oscillators. The circuit shown in Figure 1 is used as a simulation example in the current tutorial. Figure 1. An inverting unity gain operational amplifier circuit 1) Start the MultiSim program as shown in the previous tutorial (For Windows users the default location can be found by clicking: Start -All Programs - Electronics Workbench - DesignSuite Freeware Edition 9 - MultiSim 9). 2) You will be creating a new schematic and simulation so choose File-SaveAs, navigate to or create a directory where you can save this schematic and simulation then fill in the filename as shown below. (I called this one tut1.) Click OK when you have navigated to the proper directory and entered a name for the project. 3) You should now have a blank schematic. Start placing components by selecting Place- Component from the menu bar. You will see another dialog box as shown. Start with the OpAmp so pick Analog Components in the drop down menu as shown: 4) You should see a new dialog box. Select OPAMP then LM741CN as shown below then click OK.
