摘要

采用0.18 μ m CMOS工艺实现了一种用于超宽带应用的14频带频率合成器。它使用两个锁相环和三个混频器。通过使用正交除以3电路和2级单边带混频器，由于频率混合而产生的杂散至少比输出载波低35dB。核心电路面积1.5 mm2，功耗160mW

A 14-band Frequency Synthesizer for MB-OFDM UWB Application

A 14-band frequency synthesizer for UWB application is realized in a 0.18 mum CMOS process. It uses two PLLs and three mixers. The unwanted spurs due to frequency mixing are at least 35dB lower than the output carriers by using a quadrature divide-by-3 circuit and a 2-stage single-sideband mixer. The core circuit area is 1.5 mm2 and the power consumption is 160mW
