CMOS LC tank circuits and flux linkage between inductors can be used to distribute and propagate clock signals over the surface of a VLSI chip or muprocessor. A structure is placed close to the surface of the IC. This structure contains circuitry to generate RF signals. These signals can originate from individual inductors, cavity oscillators, antennas, or other forms of RF signal generation. These signals are applied to the surface of the IC and are detected by the coils of an LC tank circuit formed in the metallization. These signals are used to force each of the LC tank circuits into synchronism. In addition, the inductance of the LC tank circuit can comprise several inductors coupled in parallel. Thus, the external signal provides the stimulus to synchronize individual LC tank circuits located in the IC. |
