A clock distribution apparatus for providing a local clock signal having a first voltage swing to a circuit unit being on a same substrate includes a global clock distribution network for generating and distributing a global clock signal having a second voltage swing being less than the first voltage swing; and a local clock converting unit being electrically connected between the global clock distribution network and the circuit unit. The local clock converting unit includes a level shifter for converting the global clock signal into the local clock signal.
