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.
