Abstract :
In this paper, a low phase noise cross-coupled differential voltage controlled oscillator is designed in 0.13-¿m CMOS for use in 60 GHz applications. Using a tuned output buffer, the single-ended output voltage of 1 Vp-p is provided into a 100-fF capacitive load. Measured phase noise below -96 dBc/Hz at a 1-MHz offset is achieved, using an enhanced current sources and phase noise filter. The design has a tune range of 5% around the center frequency of 62 GHz. The low phase noise and high output drive capability make the VCO suitable for CDR circuits in IEEE 802.15.3c.a.
