In Figure 4 the LT1016’s supplies are bypassed, but it still
oscillates. In this case, the bypass units are either too far
fromthedeviceorarelossycapacitors.Usecapacitorswith
good high frequency characteristics and mount them as
close as possible to the LT1016. An inch of wire between
the capacitor and the LT1016 can cause problems. If op-
eration in the linear region is desired, the LT1016 must
be over a ground plate with good RF bypass capacitors
(≥0.01F) having lead lengths less than 0.2 inches. Do
not use sockets.
In Figure 5 the device is properly bypassed but a new
problem pops up. This photo shows both outputs of the
comparator. Trace A appears normal, but Trace B shows an
excursion of almost 8V—quite a trick for a device running
from a 5V supply. This is a commonly reported problem
in high speed circuits and can be quite confusing. It is
not due to suspension of natural law, but is traceable to
a grossly miscompensated or improperly selected oscil-
loscope probe. Use probes that match your oscilloscope’s
input characteristics and compensate them properly.
Figure 6 shows another probe-induced problem. Here,
the amplitude seems correct but the 10ns response time
LT1016 appears to have 50ns edges! In this case, the
probe used is too heavily compensated or slow for the
oscilloscope. Never use 1× or “straight” probes. Their
bandwidth is 20MHz or less and capacitive loading is
high. Check probe bandwidth to ensure it is adequate for
the measurement. Similarly, use an oscilloscope with
adequate bandwidth.
