Abstract :
Fully differential voltage-controlled oscillator (VCO) design with a low phase noise and extra linear VCO gain (Kvco) for 5-GHz wireless applications in 0.35-mum SiGe (Silicon Germanium) BiCMOS technology is discussed in this paper. The phase noise level is -120.976 dBc/Hz at 1 MHz offset at an oscillation frequency of 5.4 GHz. The Kvco changes from 214 MHz/V to 271 MHz/V. The tunability of the structure covers 786 MHz, from 4.642 GHz up to 5.428 GHz. Considering a current consumption of 3.13 mA, with 3.0 V voltage supply.
