Abstract:
A tunable inductor arrangement arrangable on a chip or substrate is disclosed. The tunable inductor comprises a first winding part connected at one end to a first input of the tunable 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 tunable inductor arrangement, a fourth winding part connected at one end to the other end of the third winding part, and a switch arrangement arranged to tune the tunable inductor arrangement. Tuning is performed by selectively provide any of a circuit comprising the first and third winding parts in series between the first and second inputs, or a circuit comprising the first, second, fourth and third winding parts in series between the first and second inputs. The first and third winding parts are arranged on the chip or substrate such that magnetic fields of the first and third windings are essentially common, and the second and fourth winding parts are arranged to cancel electro-magnetic coupling with the first and third winding parts. A receiver, transceiver, communication device, method and computer program are also disclosed.
