• This paper presents a 1.3 GHz fully integrated differential LC VCO with /spl plusmn/20% tuning range (1.0 to 1.7 GHz: including coarse and fine tuning) and tank quality factor of 6 using differential spiral inductor. The measured phase noise at 60 kHz and 900 kHz offset frequency from a 1.3 GHz center frequency is -102 dBc/Hz and -123 dBc, respectively. It consumes 10 mA at 2.7 V supply. Fabricated in 0.18 /spl mu/m SiGe BiCMOS process with 78 GHz f/sub T/, the total chip area including VCO switch cap array is 360/spl times/700 /spl mu/m/sup 2/.
