摘要：

This article presents an eight-phase low phase noise CMOS voltage controlled oscillator (VCO). The low noise CMOS VCO has been implemented with the TSMC 0.18 mu m 1P6M CMOS technology and adopts two quadrature cross-coupled nMOS-core VCOs injection-locked through the second-harmonic. The VCO operates from 5.1 GHz to 5.5 GHz with 7.54% tuning range. The measured phase noise at 1 MHz offset from 5.1 GHz is about -115.4 dBc/Hz. The power consumption of the VCO core is 7.43 mW tit the supply voltage of I V. (C) 2009 Wiley Periodicals, Inc.
