We proposed a voltage-controlled oscillator (VCO) and an injection-locked frequency divider (ILFD) at a stacking topology. The proposed circuit has its optimized performance and low power consumption. The circuit was designed in a 0.13 μm CMOS technology. The VCO's output frequency is from 11.2 GHz to 13.4 GHz while the ILFD's output frequency is from 5.6 GHz to 6.7 GHz. The total power consumption is 3.67 mW at a supply voltage of 1.5 V. Moreover, the phase noises for the VCO and ILFD are -112 and -118 dBc/Hz at 1 MHz offset, respectively.
