This paper presents a novel low-phase-noise and ultra-bandwidth LC-tank voltage- controlled oscillator (VCO). The work fully-integrated 5.8 GHz VCO designed and simulated using 130-nm CMOS technology. Instead of using the conventional varactor in the tank de- sign, a novel metal-oxidemetal (MOM) digital capacitor switching array (MOMDCSA) has been implemented with nMOS varactor is employed as an effective varactor bank. The proposed VCO- measured results at the centre frequency demonstrate a phase noise of −129.7 dBc/Hz and FOM of −198.38 dBc/Hz at 1 MHz frequency offset. The VCO shows approximately 33% tuning range under a power consumption of 2.8 mW.
