This paper reports a 12GHz Rotary Travelling Wave (RTW) Voltage Controlled Oscillator designed in a 130nm CMOS technology. The phase noise and power consumption
performances were compared with the literature and with telecommunication standards for broadcast satellite applications. The RTW VCO exhibits a -106dBc/Hz@1MHz and a 30mW
power consumption with a sensibility of 400 MHz/V. Finally, requirements are given for a PLL implementation of the RTW VCO and simulated results are presented
