摘要：

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 mu m 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 mm(2) chip area.
