1. A programmable integrated inductor comprising:
- a dual-turn inductor comprising at least one inner turn and at least one outer turn, wherein a current generated by the at least one inner and a current generated by the at least one outer turn have a same direction; and
at least one parallel programmable impedance configured to change an impedance value and an inductance value of the inductor, wherein the impedance value is a variable based as a function of a digital or an analog signal and the inductance value is programmable so that its range may be set to an unlimited number of values.

Abstract
The present invention provides a programmable integrated inductor having a compact design, having a dual turn and a parallel programmable impedance. In particular, the impedance value of the programmable changes, like a variable, programmable, as its range may be set to an unlimited number of values. The invention, thus, provides a wider range of programmable values without compromising space, at a constant equivalent given inductor area.
