Placement of the capacitor returns (grounds), where the capaci-
tors enter into the ground plane, is also important. Returning
the capacitors grounds close to the amplifier load is critical for
distortion performance. Keeping the capacitors distance short,
but equal from the load, is optimal for performance.
In some cases, bypassing between the two supplies can help to
improve PSRR and to maintain distortion performance in
crowded or difficult layouts. This is as another option to
improve performance.
Minimizing the trace length and widening the trace from the
capacitors to the amplifier reduce the trace inductance. A series
inductance with the parallel capacitance can form a tank circuit,
which can introduce high frequency ringing at the output. This
additional inductance can also contribute to increased distor-
tion due to high frequency compression at the output. The use
of vias should be minimized in the direct path to the amplifier
power supply pins since vias can introduce parasitic inductance,
which can lead to instability. When required, use multiple large
diameter vias because this lowers the equivalent parasitic
inductance.
GROUNDING
The use of ground and power planes is encouraged as a method
of proving low impedance returns for power supply and signal
currents. Ground and power planes can also help to reduce
stray trace inductance and to provide a low thermal path for the
amplifier. Ground and power planes should not be used under
any of the pins of the AD8000. The mounting pads and the
ground or power planes can form a parasitic capacitance at the
amplifiers input. Stray capacitance on the inverting input and
the feedback resistor form a pole, which degrades the phase
margin, leading to instability. Excessive stray capacitance on the
output also forms a pole, which degrades phase margin.
