摘　　要：提出了一种通过测试验证可稳定工作的多通道神经刺激器系统。该系统除实现根据不同控制信号产生不同的刺激电流脉冲,驱动不同组合电极的功能外,还综合考虑了芯片面积、功耗等方面的优化;介绍了该系统的电路结构和工作原理,给出了测试方案和测试结果,重点介绍了无线传输系统中的数据及能量恢复电路。An electrical neural stimulator system was proposed, which could produce different stimulus currents according to control data to drive different combination of electrodes. Chip area and power dissipation were minimized. Circuit structure and operational principle were described, and test schemes and test results were provided. The clock/data/energy recovery circuits in wireless transmission system were discussed in particular.
