A method for locally generating a ratio clock on a chip includes generating a global clock signal having a global clock cycle. A centralized state machine includes a counter going through a complete cycle in response to a non-integer number of global clock cycles, the state machine generating a control signal in response to the counter. The control signal is provided to staging latches, the staging latches generating a clock high signal and a clock low signal. Local pass gates generate an (n+0.5)-to-1 clock signal in response to the global clock signal, the clock high signal and the clock low signal.
