Randall,
Funny you should mention phase plane, as Dave and I were talking
about that just last night. I was getting ready to see what I could
cook up in Spice and your reference could save me some work.
For some component values, the negative-resistance circuits will have
conditionally stable feedback, which might permit oscilations to
start following a transient overload or possibly on
start-up. Looking at transients in the phase plane may help us
understand if the problem exists in a particular design and, ideally,
how to prevent any oscillation tendencies.
Thanks for the links.
Brett
