By inversely coupling two identical inverse-class-F VCO through two coupling capacitors between the gates of the active devices, the proposed VCO can achieve differential output if the size of the coupling capacitors is selected properly, and therefore gets more suppression to the disturbance of the supply voltage. Meanwhile, the proposed VCO inherits the high FoM performance of the inverse-class-F topology and achieves phase noise improvement due to the electrical coupling. Designed and simulated in 28 nm CMOS process, the post-layout simulation shows that the prototype consumes 5.26 mW from a 0.7-V supply. The PN at 1 MHz offset is −121.4 dBc/Hz when oscillating at 7.92 GHz.

Using the Transfer Matrix Method, the attenuation coefficients in different dusty plasma parameters and external magnetic fields are calculated. Results reveal that the dust concentration contributes to attenuation properties under the impact of external magnetization. Particularly, if the electron spins in the same direction as the polarized waves under the effect of the external magnetic field, a high attenuation peak and an associated attenuation band will appear at electron cyclotron frequency.
