This paper presents a wearable active concentric electrode
for concurrent EEG monitoring and Body-Coupled Communication
(BCC) data transmission. A three-layer concentric
electrode eliminates the usage of wires. A common mode averaging
unit (CMAU) is proposed to cancel not only the continuous
common-mode interference (CMI) but also the instantaneous CMI
of up to 51Vpp.The localized potentialmatching technique removes
the ground electrode. An open-loop programmable gain amplifier
(OPPGA) with the pseudo-resistor-based RC-divider block is
presented to save the silicon area. The presented work is the first
reported so far to achieve the concurrent EEGsignal recording and
BCC-based data transmission. The proposed chip achieves 100 dB
CMRR and 110 dB PSRR, occupies 0.044 mm2, and consumes
7.4 μW with an input-referred noise density of 26 nV/Hz.
