ABSTRACT:
A phase-locked loop within an integrated circuit assembly is provided. The phase-locked loop includes a plurality of subcells of semiconductor devices arranged in a base layer pattern on base layers of the integrated circuit assembly. One or more metal layers are formed over and interconnect the plurality of semiconductor devices in a metallization pattern. The phase-locked loop has an output frequency range that is changeable with a change to the metallization pattern without a corresponding change to the base layer pattern.
