Abstract
A new differential voltage-controlled oscillator (VCO) is designed and implemented in a 0.13-μm CMOS 1P8M process. The designed circuit topology is an n-core LC-tank VCO with an LC resonator. At the supply voltage of 1.1 V, the output phase noise of the VCO is −113.8 dBc/Hz at 1-MHz offset frequency from the carrier frequency of 11.73 GHz and the figure of merit is −192.01 dBc/Hz. The core power consumption is 1.83 mW. Tuning range is 1.47 GHz from 10.66 to 12.13 GHz, while the control voltage was tuned from 0 to 1.2 V. © 2010 Wiley Periodicals, Inc.
