摘要
介绍了触角传感器的地位以及模数转换器在信号采集系统中的关键作用;说明了利用混沌理论设计A/D转换器中的数学依据;基于混沌帐篷映射和开关电容(SC)技术设计了A/D转换器,该转换器具有非线性放大、便于实现集成、成本低、工作可靠等优点。用该A/D转换器设计了模拟式阵列触觉传感器信号采集系统,实验结果说明该方法是可行的。
The position of tactile sensor and key function of A/D converter in signal collecting system are introduced. The mathematics basis of A/D converter designed by use of chaos theory is explained. The A/D converter circuit is designed based on chaos tent map and switched-capacitor（SC） technique. It has advantages for nonlinear amplifying, convenience for realizing. The cost is low and the work is dependable. The signal collecting system analog array tactile er. Experiment results show that the method is sensor is designed by making use of the A/D convertfeasible.
