摘要

提出了一种采用无电感设计方法的14频带MB-OFDM超宽带频率合成器。它能够在大约2ns的时间内在整个UWB频带上进行频率切换，并且在1mhz偏移时相位噪声小于- 114 dBc/Hz。该合成器采用0.13 μ m CMOS技术，在1.2 V电源下功耗为135 mW，仅占用1.3 mm2的硅面积。

Fast hopping carrier generation for 14-band multi-band OFDM UWB in digital CMOS

A 14-band frequency synthesizer for MB-OFDM UWB using an inductor-less design methodology is presented. It is capable of frequency switching across the entire UWB band in approximately 2 nS, and the phase noise is less than −114 dBc/Hz at 1 MHz offset. Implemented in a 0.13µm CMOS technology, the synthesizer dissipates 135 mW from a 1.2 V supply, and occupies only 1.3 mm2 of silicon area.
