Input voltage source to a VPWL (piece-wise In the Graph window, choose Trace вЂ“ Add Trace, and add V( R1:1), the voltage at the load resistor:ДЄnd we have the voltage transfer function for the Sweep source V2 from 0V to 5V at 0.01V increments: MOSFET models are located in the breakout.slb library, under the names Mbreakn (NMOS) and MbreakpДЄnd enter appropriate values for the parameters. You can edit the transistor model if you wantДЄnd the frequency response shows the passband We find the specifications for the 2N2222 transistor:ДЄssumes the 2N2222 has a b of 255.9.

Here is the schematic with the bias voltagesДўN2222 transistor, and its collector is connected to Node 2, its base to Node However, it is easier to go back to the Schematic program and select Analysis вЂ“ Display Results on SchematicДЄnd/or Enable Current Display.

The theoretical value is about (RLД¬urrents, you can look at the ASCII output file. Gain of about 1.5 at a frequency of 1 kHz. Voltage is the voltage at the + terminal of V3, Since weвЂ™re interested in the gain of theД¬ircuit, we want to plot the output voltage divided by the input voltage. Will interpret this as milli (10 -3).) Now choose Analysis вЂ“ Simulate and PSpice will run, In this case we will also select AC Sweep which will give the frequencyД¬lick on AC Sweep to tell what frequency rangeДЇrequencies from 100 Hz to 1 MHz. Use the component VDC for DC power supplies, and VAC You canД¬hange the value of a component by double-clicking on the component value, andД¬omponents together by placing wires вЂ“ DrawДЄn analog ground ( AGND). Object by clicking on it to highlight it, then use Edit вЂ“ Rotate (or Ctrl-R). Need a component of the same type as one you have already placed, you can use Select the part you want and place it on the Things such as voltage sources will be in analog.slb. If the part you want is not on the list, tryДЄnother library вЂ“ parts such as transistors will probably be in eval.slb, while Which will allow you to select pats from libraries. The Draw drop-down menu, and select Get new part (or use the shortcut Start up you will get a screen which looks like this: Start with the PSpice Schematics program.

PSpice provides a free student version of its program which User interfaces for Spice, which make it much easier to use. Several companies have developed graphical Intuitive to use because the input is an ASCII file rather than a circuitДiagram, and the output is another ASCII file rather than a graph. Spice does the circuit analysis and puts out bias conditions, frequency response, and/or transient response. You then tell Spice what information you want

There is always a ground node, which is Number 0. In its original form you tell Spice whatД®lements are in the circuit (resistors, capacitors, etc.), and then enter theД¬ircuit diagram as an ASCII file showing what nodes each element is connected Program developed by the EE Department at the University of California at Berkeley for computer simulation of analog circuits.
