Abstract

See full text

A tunable inductor arrangement includes a first winding part connected at one end to a first input of the inductor arrangement, a second winding part connected at one end to the other end of the first winding part, a third winding part connected at one end to a second input of the inductor arrangement, and a fourth winding part connected at one end to the other end of the third winding part. For tuning, the inductor arrangement includes a switch arrangement switchable between a first setting series-connecting the first and third winding parts between the inputs, and a second setting series-connecting the first, second, fourth and third winding parts between the inputs. The first and third winding parts are arranged on a chip or substrate with essentially common magnetic fields, and the second and fourth winding parts are arranged to cancel electro-magnetic coupling with the first and third winding parts.
