Learn electronics with circuit simulation: Make the connection.

Useful ideas, small experiments and a reason to change one more value. Start where your curiosity takes you.

A four-switch charge-pump doubler in the desktop app: 5 V in, and a transient plot of the output climbing in steps to 9.9 V

FEATURED EXPERIMENT · POWER CONVERSION

Capacitive DC-DC converters: how a charge pump works.

See how a charge pump doubles or inverts a voltage with switches and capacitors, why its output sags under load, and simulate both circuits in Simvolta.

New to circuit simulation?

Start with your first voltage divider, then learn when to use DC, AC or transient analysis. Explore filters and model limits as you go.

Your first circuit: predict, run, understand.

Build a voltage divider, predict its voltage and current, then discover why adding a load changes the answer.

SIGNALS & INTUITION · 7 MIN READ

Read an RC filter in time and frequency.

Connect a 500 Hz transient to a 159 Hz Bode corner, and learn why startup, phase and small-signal analysis tell different parts of the story.

BETTER EXPERIMENTS · 6 MIN READ

A component symbol is not the whole component.

Understand generic devices, supported SPICE models and the limits of numerical accuracy before turning a simulated circuit into a physical one.

SIMULATION BASICS · 7 MIN READ

DC, AC or transient? Choose the analysis that answers your question.

Three analyses, three questions. Real results from a divider, an RC filter and a rectifier show when to use a DC operating point, a transient run or an AC sweep.
