ABSTRACT
By designing the circuit structure of preamplifier and selecting new elements such as ultra low noise operational amplifier and linear opto-coupler,some difficulties in EEG acquisition is overcome and the Common Mode Rejection Ratio(CMRR) of preamplifier is highly increased.So EEG can be amplified and detected well.
