Patent ID: 8446224

Claim:
A circuit interconnection structure for synchronizing a network of oscillators within a system placed on a semiconductor substrate comprising: a plurality of first synchronizing circuits, at least one first synchronizing circuit coupled to a second synchronizing circuit; wherein a first output of the first synchronizing circuit is coupled to a first input of the second synchronizing circuit through a first tunable delay; wherein a first output of the second synchronizing circuit is coupled to a first input of the first synchronizing circuit through a second tunable delay; wherein the at least one first synchronizing circuit comprises an N-input digital signal synchronizing circuit having an input stage capable of accepting a first number of N-input digital signals, and an output stage capable of outputting one or more digital output signals digital output signals; wherein the one or more digital output signals are asserted only when all of the first number of input signals are asserted; and wherein the one or more digital output signals are deasserted only when all of the first number of input signals are deasserted.
