An integrated printed inductor has a set of open petal loops, connected together in series. For a given inductance value higher quality factor and higher frequency value result using an equal chip surface area. With the same fabrication cost and equal occupied area, higher quality factor values at higher frequency can be achieved. The innovative shape is such that secondary mutual coupling effects occur and contribute to increases of overall inductance values. Small current loops arranged as petals corresponding to inductance value LO are connected in series for the inductance value to add up to a higher value. The loops are connected along a circular path to minimize the total chip area occupied. A secondary loop in the center of the inductor results in a stronger magnetic flux and a higher inductance value, due to both self inductance of the secondary loop and mutual inductance of it with the petals.
