Abstract :
MOS Current Mode Logic (CML) is featured on a 0.25 μm BiCMOS technology to implement a low noise, low power PLL operating to 1.2 GHz for portable wireless applications. It operates over 1.8 to 2.8 V and consumes 9.3 mA including the VCO. As part of a highly integrated two-chip transceiver system, full differential operation significantly reduces phase noise
