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
