In order to achieve the maximum performance of the
device, PCB layout is critical. Texas Instruments has
developed an EVM for the evaluation of the THS4271 in a
gain of one. The EVM is shown in Figure 102 through
Figure 105. This EVM is designed to minimize peaking in
the unity gain configuration.
Minimizing the inductance in the feedback path is critical
for reducing the peaking of the frequency response in unity
gain. The recommended maximum inductance allowed in
the feedback path is 4 nH. This can be calculated by using
Equation 8.

where:
W = Width of trace in inches.

.
T = Thickness of the trace in inches.
K = 5.08 for dimensions in inches and K = 2 for dimensions
in cm.
