A CMOS Power Line Communication for EEG

New Electroencephalogram - EEG systems demand larger number electrodes, such as ultra-dense EEG network. They are constituted of 256 or 512 electrodes that require a pair of wires for power supply and additional wiring for data communication (active electrodes). In order to reduce the number of wiring to a minimum, we proposed the use of Power Line Communication, over a transceiver (transmitter and receiver). The proposed transceiver was implemented in 0.18 μm CMOS technology using CADENCE tools. The circuit can operate on 1.8 DC power supply and operates at 10 M Hz.
