A 0.6-V low-power armstrong VCO in 0.18 μm CMOS

A low-power differential voltage-controlled oscillator (VCO) is proposed and implemented in a 0.18 μm CMOS 1P6M process. It consists of two single-ended Armstrong oscillators via cross-coupled transistors to obtain a differential output. At the supply voltage of 0.6 V, the output phase noise of the differential VCO is −120.02 dBc/Hz at 1 MHz offset frequency from the carrier frequency of 3.85 GHz and the figure of merit is −188.5 dBc/Hz. Total VCO core power consumption is 2.1 mW. Tuning range is about 550 MHz, from 3.81 to 4.36 GHz, whereas the control voltage was tuned from 0 to 2.0 V. © 2009 Wiley Periodicals, Inc.
