Static and Dynamic Frequency Dividers

What are the differences between the above two types of dividers, i am aware that the static type of dividers are based on D-FF′s whereas the Dynamic aproach is either based on Regenerative feedback or Injection Locking...

My question is that why are they called "Static" and "Dynamic".....is it something related to power consumption..?

Regards

I would think that the static and dynamic are more related to digital side of things. The transitor level implementation of the D-FF can be of Pull-Up/Pull Down network, E-TSPC, or TSPC which for the E-TSPC and TSPC are dynamic.

Just my thoughts.
