Measurements and 3D electromagnetic simulations highlight the efficiency of different layout techniques and technological choices to improve the integrated inductor Q factor. We compare a variable-width spiral inductor with a classical spiral inductor keeping the inductance value constant as an essential parameter for RF circuit designers. A 30% Q factor enhancement is achieved for a same size device and same inductance value. The paper will attempt to provide keys to compromise between Q factor optimization and inductor compactness. The influence of the ratio between internal and external width of the coil's turns and the wire space is also examined.Read More
