Abstract
본 논문에서는 암호화 통신응용을 위한, 트랜스콘덕터에 기반한 비선형 저항으로 이루어진 카오스 추아회로를 구현하였다. 제안하는 회로는 인덕터와 커패시터의 수동소자와, MOS 트랜지스터 기반 가변저항 및 트랜스콘덕터 기반 추아 다이오드로 이루어진다. 제안하는 회로는 SPICE 모의실험결과, 시간파형, 위상특성 및 주파수 해석 등을 통하여 다양한 카오스 다이나믹스를 보여주었다. In this paper, we designed a Chua's chaotic circuit using transcondcutor based nonlinear resistor for secure communication applications. Proposed chaotic circuit consist of passive devices such as L and C, a MOS based variable resistor and a transcondcutor based Chua's diode. From SPICE simulation results, the proposed circuit showed variable chaotic dynamics through time waveforms, frequency analysis and phase plots.
