Low-power 48-GHz CMOS VCO and 60-GHz CMOS LNA for 60-GHz dual-conversion receiver

摘要

A low-power low-phase-noise 48-GHz CMOS LC voltage-control oscillator (VCO) and a low-power 60-GHz CMOS low-noise amplifier (LNA) for 60-GHz dual-conversion receiver are reported. The VCO dissipated 5.556 mW power, and achieved state-of-the-art phase noise of -105 dBc/Hz at 1-MHz offset from 47.84 GHz. The corresponding figure-of-merit (FOM) was -191.1 dBc/Hz, which is better than those of the reported CMOS LC VCOs around 48 GHz in the literature. Besides, the LNA consumed 21.4 mW power, and achieved input return loss (S₁₁) of -10.6~ -37.4 dB, voltage gain (A_V) of 10.7~ 18.8 dB, reverse isolation (S₁₂) of -43.5~ -48.1 dB, input referred 1-dB compression point (P_1dB-in) of -16.2~ -20.8 dBm, and input third-order inter-modulation point (IIP3) of -4~ -7.5 dBm over the 57-64-GHz-band of interest.
