ELECTRICAL STIMULATION AND MONITORING DEVICE

An electrical stimulation and monitoring device comprises several signal paths which are connected in parallel with each other, and each containing a stimulation or sensing electrode (25, 35), a DC-blocking capacitor and a stimulation or sensing channel (26, 36). A semiconductor substrate (100) used for hosting the DC-blocking capacitors is connected electrically to a DC voltage source (2) througha substrate holding capacitor. Such substrate holding capacitor reduces a blanking time between stimulation and sensing periods, and also reduces cross-couplings between different ones of the signalpaths while all the DC-blocking capacitors are provided on one and same semiconductor substrate. 一种电刺激和监测装置包括若干彼此平行连接的信号路径，并且每个信号路径包括刺激电极或感测电极(25，35)、DC阻断电容器和刺激通道或感测通道(26，36)。用于容纳DC阻断电容器的半导体基板(100)通过基板保持电容器电连接至DC电压源(2)。这种基板保持电容器减少了在刺激时段与感测时段之间的消隐时间，并且还减少了当所有的DC阻断电容器都设置在同一个半导体基板上时不同信号路径之间的交叉耦合。
