Emitter Inductance and Performance
As a direct result of their circuit
topology, the performance of INA
MMICs is extremely sensitive to
groundpath (“emitter”) inductance. The two stage design
creates the possibility of a feedback loop being formed through
the ground returns of the stages. If
the path to ground provided by
the external circuit is “long” (high
in impedance) compared to the
path back through the ground
return of the other stage, then
instability can occur (see Fig. 1).
This phenomena can show up as a
“peaking” in the gain versus
frequency response (perhaps
creating a negative gain slope
amplifier), an increase in input
VSWR, or even as return gain (a
reflection coefficient greater than
unity) at the input of the MMIC.
The “bottomline” is that excellent
grounding is critical when
using INA MMICs. The use of
plated through holes or equivalent
minimal path ground returns at
the device is essential. An
appropriate layout is shown in
Figure 2. A corollary is that
designs should be done on the
thinnest practical substrate. The
parasitic inductance of a pair of
via holes passing through 0.032"
thick P.C. board is approximately
0.1 nH, while that of a pair of via
holes passing through 0.062" thick
board is close to 0.5 nH. HP does
not recommend using INA family
MMICs on boards thicker than
32␣ mils.
These stability effects are entirely
predictable. A circuit simulation
using the data sheet S-parameters
and including a description of the
ground return path (via model or
equivalent “emitter” inductance)
will give an accurate picture of the
performance that can be expected. Device characterizations
are made with the ground leads of
the MMIC directly contacting a
solid copper block (system
ground) at a distance of 2 to 4 mils
from the body of the package.
Thus the information in the data
sheet is a true description of the
performance capability of the
MMIC, and contains minimal
contributions from fixturing.
