Fully Integrated Memristor and Its Application on the Scroll‐Controllable Hyperchaotic System

In this paper, a fully integrated memristor emulator using operational amplifiers (OAs) and analog multipliers is simulated. Based on the fully integrated memristor, a scroll‐controllable hyperchaotic system is presented. By controlling the nonlinear function with programmable switches, the memristor‐based hyperchaotic system achieves controllable scroll numbers. Moreover, the memristor‐based hyperchaotic system is fully integrated in one single chip, and it achieves lower supply voltage, lower power dissipation, and smaller chip area. The fully integrated memristor and memristor‐based hyperchaotic system are verified with the GlobalFoundries’ 0.18 μm CMOS process using Cadence IC Design Tools. The postlayout simulation results demonstrate that the memristor‐based fully integrated hyperchaotic system consumes 90.5 mW from ±2.5 V supply voltage and it takes a compact chip area of 1.8 mm2.
