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 circuit 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?
Just download a SPICE circuit file from this site and simulate it with one of several free SPICE simulators available as demo versions. More…

Op Amp - All Pass Filter

This All-Pass filter does exactly what it says - pass all frequencies. So what changes across the spectrum? It's the phase (or time delay) that varies with frequency. How does it do it and what is it good for?  More...

   Improve op amp models with 2nd and 3rd poles.

Sensors, Control, General
   Test drive an instrumentation amp.
   Linearize an NTC thermistor.
   Drive a sensor bridge with a current source.

                       EXCEL / BASIC (VBA)
   Explore electronics using BASIC programming.
   Explore the operation of an ADC.
   Create waveforms with the Fourier Series.
   Check out all the topics.

“Why simulate? To understand the circuit better. You develop intuition with a simulation.”
