Hello. And welcome to TI Precision Labs discussing PSpice for TI's AC analysis. In this example, we will be using the following circuit, which can be found in the Analog Engineer's Cookbook.
Place an AC voltage source in your schematic by searching for VAC in the PSpice part search. Alternatively, you may also use the taskbar. Select Place, PSpice Component, Source, Voltage Sources, and AC. Starting from our circuit, we will select the new simulation button and enter a name for our simulation. In this example, we will name our simulation AC_Sim. Click Create, and the simulation settings menu will appear.
In the simulation settings menu under Analysis Type, select AC Sweep/Noise and set the parameters. Under AC Sweep Type, enter the start frequency as 10 hertz, the end frequency as 100 kilohertz, and points per decade as 100. Then click OK.
In order to measure the output voltage in decibels, navigate to PSpice, Markers, Advanced, and dB Magnitude of Voltage. Place the marker on the node you would like to measure by left-clicking on the wire. In this example, we will measure the output voltage. Run your simulation by pressing the Play button or by pressing F11. A new window will open with your simulation results.
That concludes this video. In summary, we discussed how to run an AC analysis in a circuit. Thank you for watching. To find more technical resources, please visit ti.com.
