| Abstract: | By designing aboratively 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 were overcome and the CMRR of preamplifier was increased highly.So EEG can be amplified and detected well. And simulation software-Pspice helps to design circuit and debug. |
| Keywords: | Electroencephalogram(EEG) preamplifier linear opto-couplers common mode rejection ratio(CMRR) anti-interference |
