Ultrawideband signal transmission using integrated dipole antennas in silicon integrated circuits

Abstract

Ultrawideband (UWB) signal transmission in Si integrated circuits was performed by use of wireless interconnects. Linear dipole antennas fabricated on a Si substrate showed UWB characteristics in the frequency range of 5-20 GHz. The signal attenuation rates of Gaussian monocycle pulse through 10 Ωcm and 2.29 kΩcm substrates were -0.08 mV/chip and -0.03 mV/chip, respectively. Pseudo random binary signals were transmitted and received between Si chips and the lowest bit error rate of 128 bit binary signal with 13.5 Gbps was 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-6</sup> . Interference of Gaussian monocycle pulses transmitted from a dipole antenna could be suppressed by use of differential mode signals instead of common mode signals.
