Title:
INDUCTOR LAYOUT HAVING IMPROVED ISOLATION THROUGH BLOCKING OF COUPLING BETWEEN INDUCTORS, AND INTEGRATED CIRCUIT DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/209377
Kind Code:
A1
Abstract:
Disclosed are an inductor layout having improved isolation through the blocking of a magnetic field coupling between inductors, and an integrated circuit device using the same. A second inductor coil is arranged so as to be spaced from a first inductor coil in the vicinity thereof in the horizontal direction, and a conductor loop is arranged in parallel on an upper part of the first inductor coil. The conductor loop offsets a part of a magnetic flux of a first time-varying magnetic field by means of a magnetic flux of a second magnetic field generated by an induced current flowing through an interlinkage with the magnetic flux of the first time-varying magnetic field generated from the second conductor coil, thereby increasing isolation between the first inductor coil and the second inductor coil, and blocking magnetic field coupling therebetween. The inductor layout improves overall performance of an RFIC by reducing magnetic field coupling between an inductor of a power amplifier (PA) and an inductor of an oscillator, when applied to the integrated circuit device such as the RFIC, so as to allow two blocks to be arranged at a close distance, thereby enabling a micro-RFIC to be implemented.
