DESIGN INFORMATION
Trace A is the time-corrected input
pulse and trace B the residue amplifier output. The light compensation
permits very fast slewing but excessive
ringing amplitude over a protracted
time results. The ringing is so severe
that it feeds through during a portion
of the sample gate off-period, although
no overdrive results. When sampling
is initiated (just prior to the sixth
vertical division) the ringing is seen to
be in its final stages, although still offensive. Total settling time is about
2.8Вµ s. Figure 9 presents the opposite
extreme. Here, a large value compensation capacitor eliminates all ringing
but slows down the amplifier so much
that settling stretches out to 3.3Вµs.
The best case appears in Figure 10.
This photo was taken with the compensation capacitor carefully chosen
for the best possible settling time.
Damping is tightly controlled and settling time goes down to 1.7Вµ s. A = 5V/DIV Settling Times

The previous results, using the
LT1468 amplifier, provide extremely …
