A multi-modulus divider includes a chain of n dual modulus divider cells in cascade and connected in a ripple configuration where the last (n-k) of the divider cells are state-parked dual modulus divider cells. The state-parked dual modulus divider cells are forced to a given logical state when the divider cell is bypassed. The state-parked dual modulus divider cells ensure that the multi-modulus divider can change between different number of cells without clock glitches or clock errors. The multi-modulus divider is therefore capable of achieving a wide division range with seamless transition between division ratios.
