Stability Boundary Conditions
DS010055-11
Note:
The areas under the curves represent conditions that may cause the device to oscillate. For curves B, C, and D, R2 and V
+
were adjusted to establish
the initial V
Z
and I
Z
conditions with C
L
= 0. V
+
and C
L
were then adjusted to determine the ranges of stability.
