Triangle VCO and other tragidies

[Ian Fritz]

Jim --

Good news! If you get a chance, I'd like to hear about what your switching
transients look like. I've finally pretty much gotten rid of mine, using a
compensation trick suggested on the ADG431 data sheet (see their cool
precision S/H circuit). A similar trick might work with your discretes.
