Test Circuit for Curve B, C, and D
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
KA and IKA conditions with CL=0.VBATT and
C
L were then adjusted to determine the ranges of stability.
