Abstract :
This paper includes 77 GHz VCO design using a coupled-line inductor with spiral-shaped electromagnetic bandgap (EBG) structure. The coupled-line inductor enhances Q due to its low substrate loss. Thus, phase noise performances of VCO can be improved. However, the length of coupled-line will be long owing to its low inductance per unit length. EBG structure is applied to reduce its size. The 3-D EM simulation is performed to show its enhancement of inductance and Q. The simulated inductance and Q of proposed coupled-line with EBG structure are 114.0 pH and 30.70 at 77 GHz, respectively. The VCO core is designed with proposed coupled-line inductor.
