摘要：An integrated circuit, such as a radio frequency integrated circuit (RFIC), has a first layer bearing first metallization patterned for defining a first inductive coil, a cond
layer bearing cond metallization patterned for defining a cond inductive coil that overlies the first inductive coil and that is magnetically coupled to the first inductive coil through a third layer interpod between the first layer and the cond layer. The third layer bears third metallization for defining an electric shield or electrostatic shield. The third metallization is patterned into a plurality of structures having shapes intended to minimize eddy currents. The electric shield is connected to further metallization that carries a ground potential. The third layer may further bear other metallization for coupling together at least two components of the integrated circuit. The integrated circuit may be fabricated by a CMOS process, and the first and cond coils may be a primary coil and a condary coil, respectively, of a radio frequency transformer. An additional electric shield may also be included, and in this ca one electric shield can be coupled to a ground potential associated with the primary coil, and the cond electric shield can be coupled to a ground potential associated with the condary coil.
