REV. A
As the closed-loop gain is increased, the larger phase margin allows
for large capacitor loads with less peaking. Adding a low value resis-
tor in series with the load at lower gains has the same effect. Figure 4
shows the effect of a series resistor for various voltage gains. For
large capacitive loads, the frequency response of the amplifier
will be dominated by the series resistor and capacitive load.

Overdrive Recovery
Overdrive of an amplifier occurs when the output and/or input
range are exceeded. The amplifier must recover from this over-
drive condition. As shown in Figure 5, the AD8091/AD8092
recovers within 60 ns from negative overdrive and within 45 ns
from positive overdrive.

Active Filters
Active filters at higher frequencies require wider bandwidth op amps
to work effectively. Excessive phase shift produced by lower
frequency op amps can significantly impact active filter perfor-
mance.
Figure 6 shows an example of a 2 MHz biquad bandwidth filter
that uses three op amps. Such circuits are sometimes used in
medical ultrasound systems to lower the noise bandwidth of the
analog signal before A/D conversion. Please note that the
unused amplifiers
’
inputs should be tied to ground.

Sync Stripper
Synchronizing pulses are sometimes carried on video signals so as
not to require a separate channel to carry the synchronizing infor-
mation. However, for some functions, such as A/D conversion, it
is not desirable to have the sync pulses on the video signal. These
