Board-to-board near mm-range proximity communication offers connector-less, sealed energy-efficient high-speed interfaces for computing devices. This work presents a 4-channel 4 pJ/b capacitively coupled interface supporting an aggregate data-rate of 32 Gb/s up to a 0.8 mm air gap. By employing a self-crosstalk cancelling coupler and self-resonance mitigating IC design, the prototype enables board-to-board high-density bidirectional signaling capability.
