An inductive-coupling link for 3-D Network-on-Chips

An inductive-coupling link for 3-D network-on-chips (NoC) is presented. Inductively coupled coils allow high-speed wireless communication between stacked chips. 35-bit parallel input data are serialized and transmitted. Silicon measurements from test chips implementing transceiver circuits, in 65 nm SOI CMOS technology demonstrate 875 Mb/s operation.
