A radar sensor for high speed moving objects is implemented using single chip CMOS UWB IC. To reduce the measuring and processing time for the fast moving target, the reliable and low power consumed envelope detection architecture is used at the expense of high resolution. The equivalent time sampling technique is adopted for UWB transceiver, employing delay locked loop and digitally synthesized impulse...
A transformer feedback low-noise amplifier (LNA) is implemented in a standard 180nm CMOS process, which exploits drain-to-gate transformer feedback technique for wideband input matching and operates across entire 2.5 ∼ 6.8 GHz ultra-wideband (UWB). The proposed LNA achieves a power gain of 11.5dB, an input return loss of greater than 15.0dB, and a minimum noise figure (NF) of 4.2dB, while consuming...
