Abstract :
This paper includes a 24 GHz VCO design in 110 nm CMOS using transformer coupled varactor and body voltage control technique. This VCO maximizes frequency tunung range by using transformer coupled varactor and PMOS body voltage control. The measured results of the proposed VCO shows 24 GHz center frequency with 6.7 % frequency tuning range. The output frequency curve has wide linear tuning region. The phase noise of the VCO is -102 dBc/Hz at 1 MHz offset frequency. DC power consumption of the VCO core is 9 mW at 1.2V VDD.
