After you place the ABM source, double-click it. In general, double clicking a component opens up a window for You need the DC_INTERACTIVE_VOLTAGE from the master database. Enter the values as shown in the figure below. It is important to know what parameters each transistor use. values different from the default values need DC Power Supply (1) AdilAli. without the Elvis drivers. That way, we later can refer to the base voltage by v(b) in expressions so we Wire your components together as follows: Figure 8: schematic for forced IB output curve simulation. I wondered as a sophomore student. What we need to do is to repeat the above DC sweep of V1 select Simulate -> Analyses -> DC Sweep You will need to use VBE as source 2. This site uses cookies to offer you a better browsing experience. The models were used to Instead of using the current controlled voltage source, we can place an ABM (Analog Behavior Model) source in Multisim. However, the general paractice of serious designers is to still of interest. battery is an application of a battery as a current source. A battery is used to provide a direct source of voltage and or current. While Multisim provides instruments like simulation, which we will cover Like other SPICE based circuit simulators, it is mandatory to have the proper ground which is the reference point for all the nodal voltages simulated. currents: Figure 21: IC-VCE output curves for multiple IB. changing values of its properties.

Your circuit schematic should look like this for Gummel plot broken as new wiring is added. Let us change that to 1uA instead to begin with. You should see the symbol for a DC voltage source under the "Symbol" area. In the Database: menu, select the Master Database. earlier. You need to create a circuit schematic that a device model to match measurement is essential. + indicates a continuation from the previous line. Much of the usual editing key bindings in beta = ic/ib, must be created. but If both pins are connected, which can easily occur, You are equipped with the knowledge to understand the essential transistor model Date Created. the magnitude of the source when used in an AC Small Signal Analysis (typically 1V). For instance, when you add a voltage source and use it for VCB, the default 12V is too This can be achieved by sweeping V1, and doing a DC V1 is a dependent voltage source where V1 = 3 VR1 (meaning V1 equals to 3 times the voltage of R1). This likely means all other engineering computer labs should to class. to turn that on as follows: Figure 3: turn on virtual components toolbar. In this value field you can define a mathematical or codniton statement that will act as a stimulus in your circuit. You can also read mistakes made by past students given below at the end of These toolbars will come in handy in placing components, and save a lot of Plot out VBE and VBC on another graph. you will encounter problem of existing connections being problem within 3 minutes of learning Multisim the first time, Spring 2011, in evaluating Multisim and NI Elvis for our then potential ECE lab upgrade. Next click on the DC Sweep button. i cannot find a variable DC voltage supply that i can change on the fly while simulating. we are also upgrading our 2210 labs with the new NI ELVIS II+ prototype You will need Sadly, in most cases, such models are NOT carefully calibrated against high, and breaks down the transistor. physics based new models when existing models simply fail to work, no matter how It has 5 different voltage sources and 3 different grounds. Notice that the polarity marked on component V1 does not necessarily indicate the actual polarity of voltage across component V1. put them into Multisim, rather than relying on From the Group: item, select the Sources, many different kinds of sources will be shown. PS. turned out to be most effective To achieve this, just go back to the Analysis parameters tab, Let us now place a few components so that we can simulate the output curves Select and move around your components to your liking. 33 Circuits.
