HANDS-ON DESIGN AND ANALYSIS WITH SPICE & EXCEL
Circuits and Applications
Design, test and modify 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...
Easy SPICE Starter!
Looking for a fun way to build your intuitive and theoretical understanding of analog circuits? Run a sim, then change a component - can you predict the change in behavior?
