Performance of Intra-Chip Wireless Interconnect Using On-Chip Antennas and UWB Radios

An intra-chip wireless interconnect system using on-chip antennas and ultrawideband (UWB) radios that operates in 22-29 GHz is studied in this paper. The on-chip antennas are meander monopoles of axial length 1 mm in silicon technology. A unique wireless channel is formed between a pair of on-chip transmit and receive antennas. The channel is characterized up to an interconnect distance of 40 mm. The system performance is evaluated in terms of bit-error-rate (BER) under the assumptions of perfect system synchronization and signal corruption from thermal and switching noises. As expected, the system performance degrades with interconnect distance and data rate. It achieves a better BER on the 5-k??.cm Si substrate than that on the 10-??.cm Si substrate.
