Open: Ultimate Electronics: Practical Circuit Design and Analysis
Hey there, I'm Mike! Nice to meet you.
The reality is that CircuitLab has grown to be quite popular. In just the last thirty days, y’all have run 361,171 simulations and used CircuitLab for 15,505.68 hours. Wow! (Hit refresh — these stats update every 60 seconds )
As a result, it takes substantial time and talent to develop, maintain, and support our infrastructure 24/7. Paid individual memberships (plus academic site licenses sold to schools and universities) keep CircuitLab up and running.
CircuitLab membership also allows you to:
As many of our users are still learning electronics, we’re also building the first online, interactive electronics textbook: Ultimate Electronics: Practical Circuit Design and Analysis which includes hundreds of CircuitLab example circuits and simulations. It's included with your CircuitLab membership.

“ CircuitLab is the best editor I have ever used. Bug-free design, excellent simulation. Well done. No more using LTSpice. ”
“ In our product development cycle, we've used CircuitLab in more places than you might expect: optimizing our analog front-end, RF matching network analysis, improving our power supply robustness, and designing and documenting test and production fixtures. ”
