本文介绍了一种用于超宽带雷达信号产生和宽带功率放大器测试的全集成多用途m序列发生器的分析、设计和特性。该发生器可以产生长度为511比特的m序列，最高数据速率为25.52 Gb/S。该发生器包括一个混频器，用于将频谱移动到更高的中心频率，以适应FCC或ECC UWB掩码。该产生器采用低成本75 GHz FT 0.25m SiGe BiCMOS工艺制造，芯片面积为1mm2。在2.85V电源下，功耗为151 mW。给出了求相移m序列反馈抽头的一种简单、直观的算法。
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 ¿m SiGe BiCMOS technology and occupies 1mm2 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.
