Abstract: The inductance has a conductor track (2) with a shape defining a determined number of concentric spirals (4, 5) and a pair of access points (6, 6) corresponding to respective ends of the track. Another pair of access points (7, 7) distinct from the points (6, 6) is arranged on a level of two respective zones (14, 15) of the track. Inductance value L1 between the points (6, 6) is higher than between the points (7, 7). An independent claim is also included for an integrated electronic circuit having an integrated plane inductance.
