Abstract :
In this paper the analysis, design and characterization of a fully integrated multi purpose m-sequence generator for UWB radar signal generation and broadband power amplifier testing is presented. The generator can generate m-sequences of 511 bits length up to data rates of 25.52 Gb/s. A mixer is included to shift the spectrum to higher center frequencies to fit into FCC or ECC UWB masks. The generator is fabricated in a low cost 75-GHz fT 0.25 mum SiGe BiCMOS technology and occupies 1 mm2 chiparea. The power consumption is 151 mW from a 2.85 V supply. A simple, intuitive calculation algorithm is given to find the feedback taps for a phase shifted m-sequence.
