Abstract
In this paper, a low-power electroencephalogram (EEG) analog front-end (AFE) with ultra-high input impedance is presented. This AFE can be utilized for both dry and non-contact biomedical applications due to its very high input impedance along with DC signal suppression. The amplifier achieves an input impedance of 45 ƒF ∥1 TΩ and a common mode rejection ratio (CMRR) higher than 110 dB. The power consumption of the proposed 8-channel AFE and its input referred noise over the 0.5–100 Hz bandwidth are 1.62 µW and 2.62 µV rms , respectively. This yields a noise efficiency factor (NEF) of 3.11. The simulations are carried out in the 180 nm standard CMOS technology using a ± 0.5 V power supply. mulations are carried out in the 180 nm standard CMOS technology using a ± 0.5 V power supply.
