Click the Add Trace button and select Plot Window Templates from the Functions or Macros drop-down menu. Select V(Vout) on the left and Bode Plot dB

You should see a plot similar to this one. The green trace shows phase and the red trace shows magnitude. Use the cursor to find the point where the

Find and mark the point where the magnitude is -3dB.

Step Response To simulate a step response, create a new project and perform a transient analysis using the same steps as above, but with a VPULSE volt

Dependent Sources The ANALOG library provides four dependent sources: E – Voltage Controlled Voltage Source F – Current Controlled Current Source

Creating Circuits Select ‘Start → Engineering → Cadence → Capture’ from the start menu. When this dialog box appears, select Allegro PCB Design CIS

In the Part List, select the part ‘VDC’ and then click the Place Part button or hit enter. Place the part by clicking in the schematic, and then press

In order to simulate a circuit, PSpice needs a ground node attached to it. Select the Place Ground tool in the toolbar. Be warned that there are mult

It is important to name the nodes you want to plot so that you can find them easily. Select the Place Net Alias tool, enter the name Vout and click O

This will bring up the Simulation Settings dialog. Click Ok to accept the default settings. Click on the Voltage/Level Marker button and place the m

The simulation results will appear as shown, with the voltages at all probes plotted. Close this window now, and return to the schematic. If the Ena
