N2 - This paper presents a low phase noise quadrature ring oscillator with new start-up circuit. The oscillator architecture is two-stage differential ring with additional pair of transition-assistance inverters. The circuit was implemented in 0.18 μm CMOS technology and the measured tuning range of the prototype device is from 1.7 GHz to 5.5 GHz and figure of merit (FOM) is -162 dB. The proposed area of application is the core of the local oscillator in a multi-standard wireless transceiver.
