Interconnect density in traditional capacitive coupling electrodes array is limited by capacitive crosstalk between electrodes. In this work, we propose an array structure where single-ended and differential pair electrodes (designed in the common-centroid structure) are alternatively placed horizontally and vertically. The proposed structure not only cancels out the crosstalk noise but also reduces the spacing requirement between electrodes. A novel self-biased fully differential receiver suppresses the common-mode coupled crosstalk in the differential electrodes. The receiver provides CMRR of 25dB and can recover wide band (10 kHz ∼ 1 GHz) signals with 32dB gain. It consumes 25 μW at 1 GHz. It is designed and simulated in a 1.5V 0.13μm CMOS technology. © 2013 IEEE.
