Abstract :
This paper presents a cross correlation based synchronization architecture between the clock of the receiver and the transmitter for ultra-wideband radio systems. The designed architecture is based on M-sequence signals instead of the conventional impulse signals. The M-sequence generator and the analog correlation circuit are fabricated on chip using a low cost 0.25μm 95GHz fmax SiGe-HBT-BiCMOS process technology. The chip is mounted on a printed circuit board (PCB) with a commercial voltage controlled oscillator. The measurement results show a low phase noise of the VCO of -66dBc/Hz at 1KHz offset and an rms jitter of 1.6ps for a 10GHz frequency and a bit rate of 20Gb/s.
