A simultaneous tri-band on-chip RF-interconnect for future network on-chip is demonstrated. Two RF bands in mm-wave frequencies, 30GHz and 50GHz, are modulated using amplitude-shift keying, while the base-band utilizes the low swing capacitive coupling technique. Each RF-Band and base-band carries 4Gbps and 2Gbps respectively. Three different bands, up to 10Gbps, are transmitted simultaneously across a shared 5mm on-chip differential transmission line. The energy per bit is 0.125pJ/b/mm in base-band, while RF-band is 0.09pJ/b/mm.
