<p>Memristors have rich dynamic characteristics and are widely used in chaotic circuit systems. It is quite challenging to construct chaotic circuits relying solely on traditional grounded memristors and grounded capacitors without the aid of a floating memristor emulator. This study analyzed the operating principle of grounded memristors and proposed a new floating memristor based on multipliers and current-feedback operational amplifiers (op-amps). Grounded memristors are mainly used in the integration operation circuits of a certain dimensional variable in traditional chaotic systems. In this study, by connecting a floating memristor in series between two voltage nodes and taking binary variables as a whole, the floating memristor is realized, and based on this, a simple implementation of chaotic circuits is achieved.</p>
