抄録

We introduce a low noise analog front-end(AFE) prototype design for dry EEG(electroencephalogram) recording. This AFE utilizes an N-path filter with sample and hold (S/H) circuit for hum noise reduction. For the first stage of the AFE, chopping stabilization technique is used for flicker noise reduction and the capacitive-feedback topology with pseudo resistor eliminates electrode offset with efficient area utilization. The programmable gain amplifier (PGA) at the third stage of the AFE can vary its magnification in the range of 10 to 640 times, therefore it can be adjusted to make the resolution high. These components are designed in 0.18 μ m CMOS process and we simulated and measured their characteristics.
