Abstract
This letter presents a phase-noise-centric design methodology of a rotary traveling wave voltage controlled oscillator (RTW VCO). Based upon this methodology, a 15 GHz multiphase RTW VCO is realized in a standard 90 nm CMOS process. Particularly, shielded coplanar striplines are exploited to provide better shielding protection and higher characteristic impedance (Z O) with comparable Q-factor than conventional coupled transmission lines. Measured results of the proposed RTW VCO demonstrates the frequency tuning range of 2 GHz, the output power level of - 11.3 dBm, the phase noise of -109.6 dBc/Hz at 1 MHz offset, the clock RMS jitter of 2 p s RMS, and the power dissipation of 12 mW from a single 1.2-V supply. The chip core occupies the area of 0.2 mm 2. © 2012 IEEE.
