Monolithically integrated circuit

An integrated circuit for radio frequency applications comprising a transistor and a spiral inductor, wherein

• said spiral inductor is arranged on top of said transistor, whereby an electromagnetic coupling between said spiral inductor and said transistor is obtained, and
• said transistor has a finger type layout to prevent any significant eddy currents caused by said electromagnetic coupling from occurring, wherein a lateral dimension of said spiral inductor and a lateral dimension of said transistor are of the same order of magnitude, and wherein said spiral inductor is formed in metallization layers of said integrated circuit, said metallization layers being separated from said transistor by a passivation layer only.

A monolithically integrated circuit comprising:

• a transistor comprising a finger type layout to prevent any significant eddy currents caused by said electromagnetic coupling from occurring and comprising multiple gate and multiple drain fingers, and
• a spiral inductor arranged on top of said transistor, wherein an electromagnetic coupling between said spiral inductor and said transistor is obtained, said spiral inductor covering at least a portion of a plurality of multiple gate fingers as seen from above, and leaving common gate and drain connections interconnecting said multiple gate and drain fingers, respectively, uncovered as seen from above.
