A LOW-POWER LOW-PHASE-NOISE 48- GHz CMOS LC VCO FOR 60-GHz DUAL-CONVERSION RECEIVER

摘要

In this article, a low-power low-phase-noise 48-GHz CMOS LC voltage-control oscillator (VCO) using standard 0.13-μm CMOS technology is reported. Low-power consumption is achieved by maximizing the equivalent parallel resistance of the LC tank, while low-phase-noise is achieved by suppressing the up-conversion of the flicker noise of the PMOS current source to 1/f{sup}3-shaped phase noise close to the carrier. The VCO dissipated 5.556 mW power, and achieved state-of-the-art phase noise of -105 dBc/Hz at 1-MHz offset from 47.85 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. The chip area was 0.94 × 0.9 mm{sup}2 including the test pads.
