New VCO on web

[Bjorn Julin]

Interesting design Ian.

Some time ago there was some people who
also tried to design a TRI vco but i
don't know if you got it working!!

Any news folks, about your TRI VCO experiments??

It is particularly interesting to be able to
use a NPN pair for the expo converter to drive
the VCO instead of the usually PNP pair that
is used for the OTA device.
