We discuss here only very simple models for the diode and BJT. Please refer to a PSpice manual for full details on these and other semiconductor devices and circuits. The resistor, capacitor, and inductor are each adequately described with a single parameter.
However, semiconductors are usually described with many parameters. In addition, many electronic circuits contain several of the same diodes or transistors. For these reasons, semiconductor devices are described with two statements. The circuit statement gives the device, the nodes that are connected to, and a model name. A separate model definition lists the device parameters. Therefore, if there are two or more of the same diodes in a circuit, each diode circuit description statement uses the same model name.
Only one model definition is then needed. PSpice contains default values for all parameters. In essence, PSpice has built-in generic models for semiconductor devices.
You only need to specify those parameter values that are different than the default values. T he diode is a two terminal device that essentially allows current conduction in only one direction. The basic low frequency diode current-voltage relationship is given by. We construct the following schematic using the part Dbreak for the diode. An Iprobe is inserted in the circuit to display the current and a Viewpoint is used to obtain the diode voltage.
In place of Iprobe and Viewpoint you can enable or disable the bias voltages and currents by using the toolbar button V and I. We must now define the model for the diode. Using the left mouse button select the diode symbol Symbol should turn red. From the Edit Menu select Model.
The dialog box appears with the following items. Click the Change model Reference button and change the model name Dbreak to a new model called Dx. Click the OK button to accept the model. The only parameter that we have changed is Is. Notice that the diode model name has changed from Dbreak to Dx. Upon simulation we see that the diode current is 1.
Use PSpice to obtain the i-v characteristic of the diode with model number D1N Sweep the input voltage from V to 15 V. Construct the following schematic.
Select the setup from the analysis menu, click the DC Sweep dialog button. The DC sweep dialog box appears. For the Sweep variable type select the voltage source, and set its name to Vss.
Using the sweep type linear, set the starting value toend value to 15 and increment to 0.
When simulation is complete probe graphic window appears. Add the trace I D1. This is the trace of the diode current versus the supply voltage Vss. We need to change the x-axis variable to V Vd to obtain the plot of diode current versus diode voltage.To obtain current and voltage in a DC circuit, the analysis is performed with the simple Load Bias Point.
If any AC sources are present in the circuit, those sources are set to zero. All capacitors are replaced by the pen-circuit, and all inductors are replaced by short circuits. From the Analysis menu, choose Setup. The Analysis setup dialog box appears.
Click the Enabled check box in the Bias Load Point option. The reference direction of current for the circuit elements is from the first listed subscript to the second one. Example 1 EEex1. Determine the node voltages for the circuit containing a Voltage-Controlled Voltage Source as shown. Determine the node voltages and the controlled current of the dependent source. With the 3. Then, the Thevenin's impedance is.
Schematics Netlist. Computes the gain and the input and output resistances and automatically sends the results to the output file. To specify the transfer function, choose Setup from the Analysis menu and open the Transfer Function dialog box.
The transfer function analysis can be used conveniently to obtain the Thevenin's equivalent circuit. The use of this analysis to obtain the Thevenin's equivalent circuit is demonstrated in the following example. Use the transfer function analysis to obtain the Thevenin's equivalent circuit for the circuit of Example 5. We want to obtain the Thevenin's equivalent circuit with respect to the 3.
The 3. To obtain the output or Thevenin's resistance, the transfer Function is enabled. In addition to the DC analysis result, the output file contains the Transfer Function analysis results as follows. The DC Sweep is similar to the node voltage analysis, but adds more flexibility. In the DC sweep, the input variable is varied over a range of values.
For each value of the input variable, the DC operating point is computed. Select the Setup from the analysis menu, click the DC Sweep dialog button. The DC Sweep dialog box appears.Released: Mar 11, View statistics for this project via Libraries.

So anyone can tell me which schematic websites those I can get both schematic symbols and PSpice models to practice? If you are using the SPB This will open up a schematic and PSpice settings if the design is a PSpice design. Also in both the SPB With the latest version of the SPB So there are plenty of options for you to get schematics and documentation to help you ramp up in Capture.
Also in both This will show you tutorials with tons of examples of PSpice. This includes samples showing all the different theorems like Ohms law, kirchoff etc.
Thank you Ole and gfruizCDN. Unfortunately I have no such resources because of lower version Cadence as you mentioned. Could you hint me some other resources, which freely access on internet? Hi, I have tried on Anyone could tell my why? Can you tell me please which examples you want to open? Or do you have any particular interest in working with Hi Roberto, all examples cannot open.

PSpice tutorials with examples
Thank you in advanced! Last seen: 1 year 11 months ago. Last seen: 2 years 6 months ago. Last seen: 1 year 10 months ago.Pspice getting started tutorials for beginners. Starting from beginners level to advance level tutorials. You will learn about this software starting from how to download and install it.
How to design and simulate digital and electronics circuits in PSpice. PSpice tutorials are used in many engineering applications for simulation purpose. For example, it is used to simulate and design electronics circuits, digital circuits and you will see the example of all of these in this complete list of tutorials. If you are taking a digital electronics course in university and you want to check output or want to verify behavior of your electronics circuits, you can use this to simulate digital circuits like digital gates, decoders, multiplexers, full adder circuits and many others.
Similarly, one can simulate analog circuit like amplifiers, oscillators with the software. So if you want to learn about this software, you should check complete guide at the end of article. In First tutorial, you will learn how to download and install this simulation and circuit design software with step by step guide.
It is a electronics circuit simulator. It is used to design and predict behavior of analog and digital electronics circuits. There are two types of versions exit for it. It has built in libraries for many electronics components like transistors, Gates, Flip Flops and many others.
So you can easily simulate many electronics circuit by easily connecting these built in components with each other. You will learn about all these components in all tutorials given below. As you know, in electrical and electronics engineering, you always need a analysis of AC and DC circuits.
So you can perform following types of analysis with the help of this software. As I have mentioned earlier, this software has many built in components. Some of the main components are given below:. When we press the simulation button. OUT file is generated and. BIN file is executed on the computer.
