Frequency divider with funnel structure

摘要

The divider divides a frequency by adapting an input for a frequency signal to be divided, where the input is provided for a control (NA) of the base level of division, and for a control (delta NA) of a division chain, and varying the NA. The chain has a division step, where a switch controlled by a divider by 2 has an input for programming data, a hold signal input for following step and a hold signal output for preceding step.
