Note:В you can rotate a component before placement by using the shortcut on your keyboard when the component is ghosted to the mouse pointer. Select the BasicВ Group, ResistorВ Family.Return to the Select a ComponentВ window.Place section AВ of the AD712SQ/883BВ component on the workspace area.Note that this component is a multisection component, as shown by the A and B tabs. Select the AD712SQ/883BВ component, as shown in the next figure:ДЇigure 3.В Selecting the operational amplifier.Select the AnalogВ Group and the OPAMPВ family.Now place the remaining circuit components using the techniques discussed in the previous steps. Close the window to return to the schematic entry window. By default, the Select a ComponentВ window keeps returning as a pop-up until you have completed placing your components.If you need multiple components you can repeat the placement steps as shown, or place one component and use copy (Ctrl+C) and paste (Ctrl+V) to place additional components as needed.Without a power and ground your simulation cannot run.Repeat steps 7, 8 and 9 to place a second DC_POWERВ component.Place the DC_POWERВ component on the schematic.Go to the SourcesВ Group again and highlight the POWER_SOURCESВ Family (if not already highlighted from the previous selection).After placing the component, the Select a ComponentВ window will open again automatically. Move the mouse to the appropriate place on the workspace and left-click once to place the component.The Select a ComponentВ window temporarily closes and the ground symbol is вЂghostedвЂ™ to the mouse pointer. Select the GROUNDВ component (as shown in Figure 2).Select the Sources Group and highlight the POWER_SOURCESВ family.The Component BrowserВ shows the component name, symbol, functional description, model, and footprint all in a single pop-up.The components (or parts) are organized into GroupsВ and FamiliesВ to intuitively and logically group common parts together and make searching easier and more effective.Finally, the User DatabaseВ is where custom components are saved that can be used only by the specific designer. The Corporate DatabaseВ is where you can save custom components to be shared with colleagues. The Master DatabaseВ contains all shipping components in a read-only format. The Component BrowserВ organizes the database components into three logical levels. The Select a ComponentВ window appears (also known as the Component Browser), as shown in Figure 2. Open Multisim by selecting All ProgramsВ»National Instrumentsвњјircuit Design Suite 13.0В»Multisim 13.0.Therefore, if R1 = R2, then the gain is equal to 2, which you will verify when you run interactive simulation in Multisim.ДЇigure 1.В Non-inverting amplifier circuit.Д«egin by drawing your schematic in the Multisim environment. The gain of this non-inverting amplifier is calculated by the expression Gain = 1 + R1/R2. For this introductory example, you will simulate a standard non-inverting operational amplifier circuit (shown in Figure 1).
