A month ago, I came across a situation where I had to amplify a voltage from 3.0V to about 8.5V to 9V. So, the first thing I could think about is using an Op-Amp with a Non-Inverting design. So, I quickly grabbed a pen and a paper and designed the circuit that would do this job. Now, I wanted to verify if my design calculations were right and if the designed circuit will actually work.
To verify my design, I had always used the trial version of Multisim, but one day I got fed up and decided to search for a free circuit simulator that I can use anytime without the hassle of licensing. And then I came across this cool free online circuit simulator known as PartSim. Below is a video that shows this circuit simulator in action.
The best part about this is, you don’t have to worry about licensing issues or installation, and if you have an account in PartSim, you can always keep a record of your designs without losing any data.
