Bias Point Simulation – 320L
Build the circuit shown. Below the circuit is a list of the parts that were used and the libraries
that they belong to. It is important that you pay attention to which library you get the parts from.
If you are running the simulation at home using the student version the libraries will be different.

You can paste Pspice schematics into Word and Powerpoint documents as well as other Pspice
documents. This is done with standard cut and paste commands.
To include the diagram in a document.
 Select the circuit
 Hit Ctrl-C (to copy to the clip board)
 Hit Ctrl-V to paste the circuit in the destination document
Bias point simulations can be sued to determine the Q-point.
To perform a bias point simulation




From the main menu: Pspice->New Simulation
Enter a name for your simulation
Hit <create>
You will see the menu below
Select Bias Point as the Analysis Type
Hit <OK>


To simulate: from the main menu: Pspice->Run
A window will pop-up that is used to display waveforms. It will be empty since you have
performed a bias point simulation. Close the window.
The toolbar icons shown can be used to toggle the display of bias voltages and currents
on the schematic.
