![]() Set the analysis type as Time Domain (Transient) and Run to Time as 0.02 seconds. ![]() We will first do a time domain simulation and later we will do a simulation in frequency domain. It will initial PSPICE and open the simulation settings window. Enter a name and click Create to create the profile.Ģ. Click on PSpice from the Menu and select new simulation profile. Set Frequency as 1KHz and amplitude as 100mV.ġ. Place Vsin as the signal input to the system. Place 1k load to the output of the amplifier.ĭ. Then Place VDC from Place Part window as the power input and set its voltage as 6V.Ĭ. This GND connection is very important, since without it OrCAD identifies the system as floating and simulation cannot be done.ī. Press G to activate ground connector and Place it in the 0v line of the circuit. Now for the simulations you have to add several components, they are Signal Source, Power and Ground and a Load.Ī. Pspice schematics placing a node update#And update the values of the resistors and capacitors by double clicking on their values.ġ0. Now place the components and connect them. Or right click on a component and you will find its option menu.ĩ. (To activate the wire, press W) To rotate components, select the component and press ‘R’. Now place the componets in order and connect them using the wire. Lets Select BC109C/E and place it on the schematic window.Ĩ. This will filter all the devices which contains the text BC109. Press ‘P’ to open Place part window and type *BC109* and press Enter. There are several variations of BC109, so lets filter them first and select one of them. Continue the same procedure by pressing ‘P’ and ‘C’ to place capacitor. Now Click OK and place 4 resistors in your schematic. First icon means the model you selected have the PSPICE model for simulation and second says you have the model for Layout (that is PCB Design) for the selected. There are two icons below the Symbol of the resistor. Press ‘P’ and then ‘R’ to select the resistor from Place Part Window.ī. Lets start placing resistors and capacitors.Ī. Press ESC to close the ‘Place Part’ windowĦ. Click on Place -> Part or press ‘P’ as the short cut, Now click on Add Librariesĭ. As the first step you have to add libraries for the project. If you expand your project overview, you can see a special icon in SCHEMATIC1 node, (like this) it implies that the PAGE1 schematic will work as the ROOT of the project, and anything we perform will apply for the schematics related (based) to the schematics in ROOT.ĥ. Pspice schematics placing a node windows#Now in the OrCAD Capture window you can see three sub windows opened, Schematic, Session log and Project Overview.Ĥ. In next window select ‘Create Blank Project’ and click OKģ. Set a Project Name and Click OK to continue.Ĭ. Select Project Type as Analog and Mixed A/D, set a location for your project, make sure the location name does not contain any spaces (for best practices). Now you have to create a project to continue.ī. Go to Start Menu -> Orcad Family Release 9.2 -> Capture CIS (Or Capture).Ģ. Calculate IB, IC, VCE and VC of following circuit. Potential Divider biased Class A amplifier. Let’s start with the transistor amplifier circuit. ![]() Thorough out this post I will discuss to draw schematic, simulate in time domain and frequency domain and design the PCB for a simple transistor amplifier with covering some of mostly used topics in OrCAD. ![]() **** RESUMING article contains the material I prepared for a presentation I have done at my university. ** WARNING: THIS AUTOMATICALLY GENERATED FILE MAY BE OVERWRITTEN BY SUBSEQUENT SIMULATIONS Could any 1 check it out and see what's wrong here? Any help will be so appreciated!!įollowing links is The curcuit schematic and error message: I 've tried to connect a ground in the circuit, and place a huge resistor between the circuit and the ground, but it didn't help. I am a starter of Pspice, and I am running a simulation by pspice, but it keeps popping up error message. ![]()
