This work presents the design of a 24-GHz digitally controlled oscillator (DCO) in an advanced 28-nm bulk CMOS technology for short-range frequency-modulated continuous-wave radar system-on-chip for mobile and Internet-of-Things devices. The power minimization is therefore the primary focus. The oscillator consumes a record low power of 1.2 mW at a 0.65-V supply voltage. It achieves a very large frequency tuning range (TR) of 5.8 GHz (27%) and a 150 kHz resolution without significantly degrading the phase noise (PN). The proposed design methodology results in a state-of-the-art −193 dBc/Hz FoM _T .

适用于低功耗 FMCW 雷达的采用 28 nm CMOS 的功耗优化数控振荡器


这项工作介绍了采用先进的 28 nm 体 CMOS 技术的 24 GHz 数控振荡器 (DCO) 的设计，适用于移动和物联网设备的短程调频连续波雷达片上系统。因此，功耗最小化是首要关注点。该振荡器在 0.65V 电源电压下消耗 1.2mW 的创纪录低功耗。它实现了 5.8 GHz (27%) 的极大频率调谐范围 (TR) 和 150 kHz 分辨率，而不会显着降低相位噪声 (PN)。所提出的设计方法产生了最先进的−193 dBc/Hz FoM _T 。
