摘要

介绍了一种用于超宽带雷达集成电路的CMOS k波段脉冲发生器。为了提供短UWB脉冲信号，采用了基于载波的脉冲发生器，它结合了压控振荡器和有源射频开关对LO信号进行加窗处理。中心频率和带宽的可调性分别为22.3 ~ 25.2 GHz和0.18 ~ 3 GHz。UWB脉冲发生器采用65nm CMOS工艺制造，单路1.2 v电源消耗21.3 mW。

A K-band VCO-based Impulse Generator for UWB Radar Sensors

A CMOS K-band impulse generator for UWB radar IC is presented. To provide the short UWB impulse signal, a carrier-based impulse generator is employed, which combines the VCO and active RF switch for windowing the LO signal. The tunability of the center frequency and bandwidth are 22.3 - 25.2 GHz and 0.18 - 3 GHz, respectively. The UWB impulse generator is fabricated in a 65 nm CMOS process and consuming 21.3 mW from a single 1.2-V supply.
