Some embodiments of the present disclosure relate to a fractional divider for frequency generation. The fractional divider includes a permutation network including a plurality of phase input terminals and a plurality of permuted phase output terminals with a plurality of propagation paths extending therebetween. Multiple propagation paths extend between a phase input terminal and a permuted phase output terminal. A control unit switches an input signal on the phase input terminal through the multiple propagation paths in time to produce a permuted phase signal on the permuted phase output terminal. A phase selection element individually switches the permuted phase output terminals to an output terminal of the fractional divider in time to generate an output signal. The output signal has an output frequency that is a non-unity fraction of an input frequency of the input signal. |
