ON CHIP INDUCTOR WITH FREQUENCY DEPENDENT INDUCTANCE |
摘要 |
A set of metal line structures including a signal transmission metal line and a capacitively-grounded inductively-signal-coupled metal line is embedded in a dielectric material layer. A capacitor is serially connected between the capacitively-grounded inductively-signal-coupled metal line and a local electrical ground, which may be on the input side or on the output side. The set of metal line structures and the capacitor collective provide a frequency dependent inductor. The Q factor of the frequency dependent inductor has multiple peaks that enable the operation of the frequency dependent inductor at multiple frequencies. Multiple capacitively-grounded inductively-signal-coupled metal lines may be provided in the frequency-dependent inductor, each of which is connected to the local electrical ground through a capacitor. By selecting different capacitance values for the capacitors, multiple values of the Q-factor may be obtained in the frequency dependent inductor at different signal frequencies.
