Discrete Sequential Implementation of Chaos Oscillators for FPGA Integration

The current work focuses on implementing chaos oscillators in sequential logic form for the field-programmable gate array (FPGA) operation. The paper develops MATLAB models that emulate the dynamics of Vilnius and RC chaos oscillators in fixed-point arithmetic. The developed models are verified by performing Pecora-Carroll synchronization with the oscillator circuits. This study demonstrates that the developed models reflect the performance of chaos oscillators and the possibility of analog-discrete chaotic synchronization.
