Analog Intuition

Build real engineering intuition.
Visually.

A growing collection of interactive tools that help engineers feel how circuits and systems behave — not just calculate them.

Built by Joseph Spencer, Field Applications Engineer at Analog Devices. These tools grew out of real conversations with engineers who wanted faster, more visual ways to develop intuition for analog and power electronics.
