The present paper describes the design of two stimulators (bench-top and portable) which can be used for animal studies in cochlear implants. The bench-top stimulator is controlled by a high-speed digital output board manufactured by National Instruments and is electrically isolated. The portable stimulator is controlled by a personal digital assistant (PDA) and is based on a custom interface board that communicates with the signal processor in the PDA through the secure digital IO (SDIO) slot. Both stimulators can provide 8 charge-balanced, bipolar channels of pulsatile and analog-like electrical stimulation, delivered simultaneously, interleaved or using a combination of both modes. Flexibility is provided into the construction of arbitrary, but charge-balanced, pulse shapes, which can be either symmetric or asymmetric.
本文描述了两种刺激器（台式和便携式）的设计，它们可用于耳蜗植入的动物研究。台式刺激器由美国国家仪器公司生产的高速数字输出板控制，并且是电隔离的。便携式刺激器由个人数字助理（PDA）控制，基于一个定制接口板，该接口板通过安全数字输入输出（SDIO）插槽与PDA中的信号处理器通信。两种刺激器都可以提供8个电荷平衡的双极通道，用于脉动和类模拟电刺激，可同时、交错或使用两种模式的组合进行传输。在构建任意但电荷平衡的脉冲形状方面具有灵活性，这些脉冲形状可以是对称的或不对称的。
