An Ultra-wideband and Low Phase Noise LC-VCO Using NMOS Varactor with MOM Digital Capacitor Switching Arrays

摘要：

　　This paper presents a novel low-phase-noise and ultra-bandwidth LC-tank voltagecontrolled 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 design, 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 1MHz frequency offset. The VCO shows approximately 33% tuning range under a power consumption of 2.8mW.
