INDUCTOR LAYOUT HAVING IMPROVED ISOLATION THROUGH BLOCKING OF COUPLING BETWEEN INDUCTORS, AND INTEGRATED CIRCUIT DEVICE USING SAME
Disclosed are an inductor layout and an integrated circuit device with improved isolation between inductors through shielding magnetic coupling between the inductors. first and second inductor coils are horizontally spaced apart from each other. A conductor loop is disposed in parallel above the first inductor coil and shields magnetic coupling between the first and second inductor coils in the manner that a part of magnetic flux of a first time-varying magnetic field generated by the second inductor coil is cancelled by magnetic flux of a second magnetic field generated by an induction current that flows in the conductor loop magnetically interlinked with the first time-varying magnetic field. The inductor layout can be applied to an RFIC device to reduce magnetic coupling between inductors of a power amplifier and an oscillator. Improved performance of the device and a very small RFIC can be achieved.
