Abstract
An integrated circuit having a resonant circuit is provided. The resonant circuit may include an inductor and a capacitor coupled in parallel. The inductor may be formed in a dielectric stack on a semiconductor substrate. An inductor shielding structure may be interposed between the inductor and the semiconductor substrate in the dielectric stack. The inductor shielding structure may be a closed loop structure that is electrically floating. The inductor shielding structure may also be formed using arouting arrangement that is symmetrical to help cancel out any induced current from the inductor. A resonant circuit formed in this way may exhibit an enhanced Q factor.
