摘　　要：基于开关电流技术实现了Tent映射离散时间混沌电路。该电路可由16个MOSFET和2个电容实现。电路仿真和用IC搭建的电路实验证明了电路设计的正确性。实验结果表明所提电路可用标准的CMOS技术集成,而且对研究和应用混沌有意义。Discrete-time chaotic circuits realizing a tent map is synthesized using on switched-current （SI） techniques. The proposed circuits can be constructed with 16 MOSFET＇ s and 2 capacitors.The simulation and experiment built with commercially-available IC s have demonstrated the validity of the circuit design. The experiment result also indicates that the proposed circuit is integrable by a standard CMOS technology. The implementation is useful for studies and applications of chaos.
