Abstract

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^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^2^ including the test pads. © 2009 Wiley Periodicals, Inc.
