Combating fractional spurs in phase locked loops to improve wireless system performance in Beyond 5G

Scientists from Tokyo Tech propose two design techniques to minimize unwanted signals known as fractional spurs, which degrade phase noise in output of the PLL. The first technique uses a cascaded-fractional divider and achieves a -62.1dBc fractional spur, while the second technique employs a pseudo-differential DTC, resulting in an in...

Laboratory study on conditions for spontaneous excitation of "chorus emission," wave of space plasma

Researchers successfully conduct laboratory studies on whistler mode chorus emission using the RT-1 device, a magnetically levitated superconducting coil. The findings reveal that high-temperature electrons drive the generation of chorus emission, while increasing plasma density suppresses its occurrence.
