We show how to build an inductorless version of the classic Chua's circuit. The goal is to build Chua's circuit quickly and easily. To this end, only off-the-shelf components are used. A suitable inductor for Chua's circuit is often hard to procure. Here, the inductor is replaced by a single op-amp synthetic inductor circuit. The synthetic inductor is novel in the sense that it is not a gyrator, it is a one port device and thus a simple black-box analogy to an inductor is possible. We illustrate the robustness of the synthetic inductor by synthesizing two different inductor values.
