| Research Abstract |
Ultra-wideband characteristics of Sierpinski carpet fractal antennas fabricated on silicon substrates with the resistivities of 2290 Ω-cm, 79.6 Ω-cm and 10 Ω-cm were investigated. The return losses lower than-10 dB and high transmission gains of approximately-14 dB were obtained for the antennas with 10 mm distance on the Si substrate with the resistivity of 2290 Ω-cm in the frequency range from 18 to 26.5 GHz. Gaussian monocycle pulses with 70 ps pulse width were transmitted in the Si substrates successfully and the corresponding voltage gains were-23 dB,-26 dB and-39 dB for the Si resistivities of 2290 Ω-cm, 79.6 Ω-cm and 10 Ω-cm, respectively.
Ultra-wideband impulse based radio system uses Gaussian monocycle pulse as a transmitted signal at transmitting end and as a template signal at receiving end. In this paper we present a new fully integrated differential Gaussian monocycle pulse generator in 0.18 pm CMOS technology. Here the differential Gaussian monocycle pulse is generated from triangular shaped pulse by a single differentiator circuit and it is then converted into differential form by using a single input to dual output amplifier. The developed circuit occupies a small area of 0.06 mm^2 and consumes a total power of 44 mW from 1.8 V. The transmission of the generated differential Gaussian monocycle pulse at a rate of 1.4 Gbps through integrated dipole antenna in the same Si-substrate for intrachip communication in future ULSI is verified by simulation and results are presented here.
