ECE 340 – Electronics I PSPICE Tutorial 1 Using PSPICE to Analyze Operational Amplifier Circuits In this tutorial you will learn to use PSPICE to simulate circuits that include an operational amplifier. It is assumed that you already know the basics of running Orcad PSPICE. If you are not familiar with PSPICE start with Tutorial 0. 1. An operational amplifier circuit is shown in figure 1. Enter the circuit as you have done before. Note that: The operational amplifier is uA741 in the Eval Library. A positive and negative DC power supply is connected to the op amp. The sinusoidal source input (on the left) is the element VSIN.

Unformatted text preview: By double clicking on each of the following values on the source you can set their values to: VOFF = 0 VAMPL = 1 FREQ = 1000 2. Perform a transient analysis. In order to view five cycles of the waveform, run the analysis for 5 mS (enter 5m in the Run to Time box in the Simulation Setting window). Run the simulation and view the input, and output waveforms. Confirm that the gain of the amplifier matches that of your calculation. 3. Decrease the voltages of the two-dc supplies to +5 and - 5 volts. Run the simulation again. Note that the lower values of the DC supply are limiting the output voltage. Figure 1. Op Amp Circuit...
