A novel wireless interconnect technology using impulse radio for interchip communications

This paper presents a novel wireless interconnect technology using impulse radio for interchip communications. The performance analysis of a binary phase-shift-keying (BPSK) impulse radio shows that a high data rate of 2.5 Gb/s with a low bit error rate <10^-6 over an interchip wireless channel of length 20 cm can be achieved with the radiated power spectral density less than -41 dBm/MHz. The hardware design of the BPSK ultra-wideband (UWB) impulse radio realizes transmitter and receiver integrated circuits in 0.18-μm CMOS and antenna in a low-temperature cofired ceramic processes. Due to the current design and process limitations, the prototype impulse radio achieves a maximum data rate up to 200 Mb/s over the interchip wireless channel of length 20 cm with a total power consumption of 120 mW. The feasibility of using UWB impulse radio for Gb/s interchip wireless communication is addressed.
