Embodiment Construction
[0038] figure 1 The block diagram of the internal structure of the EEG signal collector is shown. The EEG data collector has a single-channel amplifier, and three electrodes are respectively fixed on the top of the head and the earlobes on both sides. The other two electrodes were connected to the differential input of the EEG preamplifier INA128. Then, through the amplification and filtering link formed by AD8606, it is sent to the ADC for sampling, and after isolation, it is sent to the PC for analysis through the USB interface. The EEG data collector is powered by the USB bus. After the 5V of the USB bus is isolated by DCDC, it is regulated to 4V by LT1962 to supply power to the amplifier part. The noise of the analog power supply part can be controlled at 20uV RMS the following.
[0039] EEG amplifier gain is 20000, common mode rejection ratio CMRR≥100dB, input resistance ≥100M, short circuit noise ≤1μV PP , Frequency bandwidth: 0.3~60Hz. Main technical indicators of A...
