Book
"Elegant Circuits is a good jump-off point for chaotic circuits, one that is accessible and practical. And while the essence of this book is down to earth, it will point your way to the clouds as well."
This book presents a collection of the simplest chaotic circuits, organized by fundamental electronic components such as diodes, transistors and memristors. It provides an in-depth exploration of the work done in the existing literature along with details of their operation. The book additionally includes our original research contributions such as new simplifications to classic chaotic circuits and novel circuits featuring solid-state memristors.
