clock divider schems ...

The doubler in the VCDO is interesting. It really just makes a spikes on
the rising and falling edges of the input, effectively doubling the
frequency, but it's a very simple circuit.
(You should keep in mind that these are pretty narrow output pulses though.)

What I've tried only as an experiment and would be neat to develop further
(anyone? :) would be to cascade these doubler stages (possibly with a one
shot or flip flop in between stages).
The input frequencies imperfections (especially from an analog vco) could
be "amplified" ie:- a 2 hz deviation x2 (4hz) x2 (8hz) x2 (16hz) x2 (32hz).
Maybe multi-tapped outputs? Feedback loops? :)

Any thoughts on cascaded freq doublers?
