Memristor act as typical analog memory and are two terminal switching devices operates at extremely low-power input. Not only can these devices offer powerful computation but also exhibit chaotic or random behavior used for Cybersecurity applications1. Memristors or ReRAMs are suitable for implementing chaotic circuit and the true random number generator (TRNG). In result, we would have a functional chaotic circuit and the oscilloscope will produce a waveform based on the Chua’s circuit that produces chaotic behavior2. Experiment is performed using two Dig-pot’s and connected wires to the specified ports onto the breadboard with DC power supply of 15 V. Two of the 2 k and 500 resistors are connected in series to the dig-pot’s. The function generator is fixed to a frequency of 100 Hz. V-t, I-t are measured in the oscilloscope. Also, memristor circuits are studied as a voltage controlled series resistors of RON and ROFF and simulated by PSPICE. Voltage-time (V-t) and current-time (I-t) variation is studied for RON/ROFF. The PSPICE modeling results can be compared to the data obtained from the microcontroller-based chaotic memristor emulator circuit. References: R. Carboni and D.

Role: The task was to build a chaotic circuit from scratch that exerted chaotic behavior within the oscilloscope. Along with this, create the circuit through a virtual simulation in electronic software's.
