摘要:
根据脑电信号的特性,提出一种适用于检测脑电信号的电极芯片的系统设计方案,分析系统所涉及的主要模块的实现技术.系统采用双铝双多晶(DPDM)标准的0.6μm互补金属氧化物半导体(CMOS)工艺完成系统信号处理电路的设计,同时采用单片集成微机电系统(MEMS)的工艺技术完成检测电极的制造,检测电极为4 mm×4 mm,电极针头长度为30~50μm,针头间距为100~210μm.系统的滤波模块主要是带通滤波电路,通带范围为0.5~50 Hz,低噪声放大电路和可调增益放大器采用基于斩波的差分差值放大器(CHS-DDA)技术,而连续时间滤波器则采用转导-电容(Gm-C)技术.
Abstract:
According to the feature of electroencephalogram(EEG),a system design for EEG signal detecting is proposed,and the realized techniques of the main modules in the system have been analyzed.The design of this EEG chip based on double poly-silicon and double metal(DPDM) 0.6 μm complementary metal oxide semiconductor(CMOS) model is described in this paper.The single integrated micro electro mechanical systems(MEMS) technique has been used to make the detecting electrode which is 4 mm×4 mm,the length and space of the electrode is 30~50 μm and 100~210 μm respectively,the main filter of the system is band pass filter whose band-pass is 0.5~50 Hz.Low noise amplifier and the tunable gain amplifier are utilized the technique based on chopper-stabilized differential difference amplifier(CHSDDA) while the continuous time filter is based on capacitance(Gm-C) technique.
