Abstract
A method for forming a spiral inductor () or component of a transformer, compatible with very large scale integrated processing, that achieves a higher Q value without occupying more space by splitting at least one turn () as two or more crisscrossing or interwoven smaller-width turns (). The at least one turn () may, for example, be split into four turns paired up to provide two pairs of two turns, and the turns of each pair may then be interwoven or crisscrossed, and then the two pairs may also be interwoven or crisscrossed. The splitting of a turn into two or more smaller-width turns results in the current being divided among the smaller-width turns.
