A fully integrated ring type voltage-controlled oscillator (VCO) for IEEE802.3ae type 10GBASE-X has been realized and characterized. It was designed and fabricated in TSMC 0.18 μm mixed signal CMOS technology. The total chip size is 0.3×0.4 mm^2. At a supply voltage of 1.8 V, the measured power consumption is 78 mW with DC-coupled differential 50 Ω loads. The linear voltage-controlled frequency area is 2.8～4.0 GHz and the phase noise of single sideband is about-96 dBc/Hz at 10 MHz offset from the center frequency of 3.125 GHz.
