tive load. Note that in each case, gain peaking is
substantially reduced when the 20
resistor is used to
isolate the capacitive load from the amplifier output.
AC Testing/Performance
AC specifications on high-speed amplifiers are usually
guaranteed without 100% production testing. Since
these high-speed devices are sensitive to external para-
sitics introduced when automatic handling equipment is
used, it is impractical to guarantee AC parameters
through volume production testing. These parasitics are
greatly reduced when using the recommended PC
board layout (like the Maxim EV kit). Characterizing the
part in this way more accurately represents the amplifi-
er’s true AC performance. Some manufacturers guaran-
tee AC specifications without clearly stating how this
guarantee is made. The AC specifications of the
MAX4180–MAX4187 are derived through worst-case
design simulations combined with a sample characteri-
zation of 100 units. The AC performance distributions
along with the worst-case simulation results for
MAX4180 and MAX4181 are shown in Figures 8–11.
These distributions are repeatable provided that the
proper board layout and power-supply bypassing are
used (see Layout and Power-Supply Bypassing sec-
tion).
