EECS 70LB Spring 2011 Notes on Lab 2: Op Amp Circuits To model an Op-Amp on PSPICE, one can use an actual Op-Amp chip (LM324), which is located under EVAL library in PLACE PART. *Remember the Op-Amp needs a DC voltage source on both V+ & V- in order to operate. To run the transient analysis in PSPICE, you need to use a sinusoidal voltage source, in this case we can use VSIN under SOURCE library in PLACE PART.

where VOFF is the offset voltage (equals to zero), VAMPL is the amplitude and FREQ is the frequency of the signal. The schematics of an inverting amplifier (under AC bias) should look like this: To place a probe (telling PSPICE where you want to take a transient reading), select the icon (circled) and place it onto the circuit. It will stick onto the circuit shown above. One then go to PSPICE/NEW SIMULATION PROFILE to create a new PSPICE

simulation, select TIME DOMAIN (TRANSISENT) for analysis type. There are two parameters to consider:
