Integrated circuit
An integrated circuit includes a main clock tree, a reference clock trunk, a reference clock buffer and a calibration circuit. The main clock tree transmits a main operation clock to an internal node via serially-coupled buffers to form a local clock at an internal node. The reference clock buffer transmits a main reference clock via the reference clock trunk to form a reference clock at a terminal node. The calibration circuit compares phases of the local clock and the reference clock to accordingly generate a control signal, so the main clock tree can adjust phase of the local clock according to the control signal.
