Abstract—An architecture to compensate the voltage attenua-
tion introduced by 3-D capacitive coupling is proposed. The scheme
is based on a calibration channel which sets the gain of the variable
gain amplifiers of the signal channels in such a way as to compen-
sate for the voltage attenuation. Based on this architecture, a pro-
totype has been designed aimed at demonstrating that 3-D
