Design of a High Performance 5.2 GHz Low Phase Noise Voltage Controlled Oscillator Using 90nm CMOS Technology

In this paper, a novel Figure of Merit (FOM), low phase noise, LC-tank voltage-controlled oscillator (VCO) is presented. The work presents a fully integrated 5.2 GHz VCO designed in a 90nm CMOS process. The proposed VCO features a worst-case phase noise of -130.10dBc/Hz and -133.00 dBc/Hz at 600 kHz and 1 MHz frequency offset from 5.2GHz carrier is achieved. An optimization technique is used to design the excellent FOM. The FOM is -206.02dBc/Hz. It features a supply voltage of 2.7 V, with a core of only 0.5 mA.
