Abstract

A low phase noise, small power dissipation and small sized K-band cascode differential voltage-controlled oscillator (VCO) with capacitive feedback topology using 0.18 μm CMOS technology is described. The VCO operated can be tuned between 19.1 GHz and 20.9 GHz and has low phase noise of -108.67 dBc/Hz at a 1 MHz offset. The output power of the 20.7 GHz is about -21.12 dBm. The Figure of merit (FOM) is -186.2 dBc/Hz and the power-frequency tuning-normalized figure-of-merit (PFTN) is -8.89 dB. The power consumption of the VCO was 10.8 mW from a 1.8 V power supply with only 0.46 mm² chip area.
