How to check the negative resistance?
(1) Connect the resistance (R) to the circuit in series
with the crystal resonator.
(2) Adjust R so that oscillation can start (or stop).
(3) Measure R when oscillation just start (or stop) in
above (2).
(4) Get the negative resistance
-R = R + CI value.
(5) Recommended -R
-R> CI * (5 ~ 10)
