This paper presents the design methodology, simulation and measurement results of a CMOS 12GHz Rotary Travelling Wave Voltage Controlled Oscillator. The different simulations (electrical using SPICE and electromagnetical using HFSS) are presented. These results are compared to a theoretical approach and measurements. The oscillator has been fabricated in a 0.13µm RF-CMOS technology. The phase noise at a 1MHz offset from the carrier is105dBc/Hz and the tuning range is 1.2GHz for a global consumption of 25mA.
