A Single-Chip Ultra-Wideband Receiver With Silicon Integrated Antennas for Inter-Chip Wireless Interconnection

A single-chip ultra-wideband (UWB) receiver was developed using 0.18 mum CMOS technology, and inter-chip wireless data communication by integrated antennas was confirmed. Timing pulse and data pulse with on-off keying were alternately sent from a transmitting antenna. Double Gaussian monocycle pulse (GMP) template generators performed detections of timing and data pulses. A single GMP template, whose probability distribution of the pulse repetition cycle is given by Gaussian, showed a random jitter of 4.87 ps. Dual-Dirac model could explain the probability distribution of the cycle of double GMP template. Obtained random jitter and deterministic jitter were 4.6 ps and 14.4 ps, respectively. The receiver successfully recovered 200 Mbps data at the distance of 0.5 mm.
