LTSpice: Simulating a Potentiometer (064a)

In this video I will show you how to simulate the action of a potentiometer in LTSpice, the FREE circuit simulation program from Linear Technology (Analog Devices). You will find a LINK below to the FREE download of this awesome program.
If you do it this way, you get to see the results of ALL of the values that you have chosen to simulate in a single simulation result. You will be able to navigate these results and determine the value of the potentiometer that will give you your desired results.
You will find a LINK to the LTSpice model file that I used in this demonstration below for your convenience.

You are very welcome! 🙂

*1. Greetings!
You're videos are extremely interesting and very detailed!
Thank you very much!
Best regards from Russia

[@eie_for_you]

Thank you for the encouragement. I am glad you have found the videos helpful. You are very welcome! 🙂

[@dougclark6696]

Thanks, Ralph. You inspired me to install LTspice!

[@eie_for_you]

You are welcome! You will love the program! It is so much fun to do all sorts of virtual experiments. I often use it to verify designs or test theories before I break out the soldering iron. And it is generally very accurate in its results to the real world. 🙂

[@johnclements3441]

Another excellent explanation. Wish I learned that one years ago.

[@eie_for_you]

Believe it or not ... after *years* of using LTSpice, I only recently took the time to figure this out. 🙂

Thank you sir I was trying to simulate a RF amplifier biasing circuit using a variable resistor, but soon found out LTSpice doesn't have potentiometers. I'll try your way of simulating a pot and see what happens.

I think you will find it pretty slick! 🙂
