  • Clock circuit with delay functions and related method
    Patent number: 8536920
    Abstract: A clock circuit with delay functions includes a first clock tree and a delay module. The first clock tree provides a first clock signal and includes a first clock root and a plurality of first sub-trees. The delay module is coupled to the first clock root or a designated sub-tree among the plurality of first sub-trees for delaying the first clock signal. The delay module includes at least two delay segments, wherein each delay segment includes a delay and a connection net. The delay time caused by each delay segment is substantially the same.
    Type: Grant
