Abstract

This paper describes a single-PLL, fixed-oscillator, wide-band multi-tuner HD Radio & DAB/T-DMB receiver for concurrent multi-band & multi-channel car radio reception, fully integrated in a 65nm CMOS SoC. Besides saving area and power for the LO and clock generation, the presented architecture also prevents oscillator pulling and spurs. Harmonic rejection mixers have been used to suppress down-conversion with LO harmonics up to 60dB, which reduces the required amount of RF filtering. The DAB measurement results show best-in-class blocker performance (FoS up to 70dBc) in combination with state-of-the-art sensitivity down to -102dBm.
一种宽带单锁相环射频接收机,用于同时接收多波段和多通道数字汽车无线电
本文介绍了一种单锁相环、固定振荡器、宽带多调谐器高清收音机和DAB/T-DMB接收机,用于并发多频段和多通道汽车无线电接收,完全集成在65nm CMOS SoC中。除了为本LO和时钟的产生节省面积和功耗外,该结构还可以防止振荡器的拉拔和杂散。谐波抑制混频器已被用于抑制LO谐波高达60dB的下变频,从而减少了所需的射频滤波量。DAB测量结果显示了同类最佳的阻挡性能(FoS高达70dBc)以及最先进的灵敏度(低至-102dBm)。
