HANDS-ON DESIGN
WITH SPICE AND JAVASCRIPT!

CIRCUITS AND APPLICATIONS
Design, test and modify these circuits using the SPICE simulator: Op amps, filters, sensors, switch-mode power supplies, PID controllers, audio amplifiers, etc. Explore circuits on your own or use the tutorials to get you started. Go to collection...

WHAT IS SPICE?
Simulate circuits on your PC. View voltage and current waveforms, frequency responses or bias points. Then change values, add components. SPICE is a great tool - you can learn a lot in a short time! More...

WHERE CAN I GET SPICE?
Free demos and downloads. More...

HOW DO I RUN SPICE?
Simply download a SPICE circuit file from this site and simulate it with one of several free SPICE simulators available. More...

EE CALCULATOR SERIES!

R Divider Calculator

rdivider

Enter any two of three parameters R1, R2 or K. Then find the remaining parameter using JavaScript. Try it!

Use the EE Calculator Series as templates to build your own JavaScript and HTML library.

DESIGN TOPICS

I am an engineer, but what I find important and necessary is that you just learn things as you go along.
