This paper presents a capacitive-coupling technique for multi-phase oscillators. The proposed capacitive coupling techniques can improve the phase noise performance while maintain good phase accuracy over wide frequency range for multi-phase oscillators. A prototype two-phase VCO is analyzed using injection-locking theory and implemented to demonstrate the effectiveness of the capacitive-coupling technique for low-power and low-noise multiple phase clock generation. The 4.3-5.3 GHz two-phase VCO prototype was implemented in a 130 nm CMOS technology and achieved a measured phase noise of -120 to -124.04 dBc /Hz @ 1 MHz offset and a measured phase error of 0.23-0.91° across the 1 GHz tuning range. |
