This is very difficult to acheive with any sort of repeteability or
wavehape. The problem is that
the (current)/(capacitance) ratio is so small that parasitic effects
dominate. Stuff like reisistance of the capacitor, leakeage,
pcb surface leakage (a small fingerprint is enough to cause the VCO to stop
working at these low speeds).
It CAN be done but you wouldn't want to pay $17 for the Teflon capacitor!
As far as other analog LFOs that claim this type of range: bull-hockey!
