Abstract :
In this paper, we present the design of 15-GHz frequency synthesizer for 60-GHz WPAN. The PLL generates 7 channels of output signals with 250 MHz step by using the highspeed programmable divider operating up to 10 GHz. A double cross-coupled LC VCO is used for achieving higher oscillation frequency and shows about 20 % tuning range. The PLL represents phase noise of -88 dBc/Hz at 1 MHz offset from 15.75 GHz and consumes 115 mA at 2.5 V supply voltage. The PLL occupies 0.7 times 0.8 mm2 area and is fabricated using 0.25 mum SiGe:C BiCMOS process technology.
