ADJUSTABLE INDUCTOR CIRCUIT, TRANSCEIVER, METHOD AND COMPUTER PROGRAM Russian patent published in 2017 - IPC H01L23/522 H01F21/12 H03J5/00 H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: adjustable inductor circuit, a radio-frequency transceiver or receiver with a resonator having such circuit, a communication device, a method for adjusting the mentioned inductor circuit are proposed. The adjustable inductor circuit is located on a chip or a substrate. The adjustable inductor comprises the first winding part connected at the first end to the first input of the adjustable inductor circuit, the second winding part connected at the first end to the second end of the first winding part, the third winding part connected at the first end to the second input of the adjustable inductor circuit, the fourth winding part connected at the first end to the second end of the third winding part and a switching circuit configured to adjust the adjustable inductor circuit by selective securing of a chain comprising the first and fourth winding parts connected in parallel and the second and third winding parts connected in parallel, wherein the parallel links are connected in series between the first and second inputs (INP, INN), or a chain comprising successively connected first, second, fourth and third winding parts between the first and second inputs.

EFFECT: ensuring stability and reliability of communication.
