Abstract

This paper proposes a new chaos generator circuit with a current sampling scheme. This circuit generates an arbitrary nonlinear function corresponding to the time-domain current waveform supplied from an external source by using a pulse phase modulation approach. The circuit designed using a 0.25 mum CMOS process has been evaluated by HSPICE simulation compared with the voltage-sampling mode chaos generator circuit that one of the author proposed before. The HSPICE simulation results demonstrate that the proposed circuit can generate chaos even if D/A conversion is used for nonlinear waveform generation, because a current integral by sampling with a short pulse smooths the quantized nonlinear function
