LAYOUT, GROUNDING, AND BYPASSING CONSIDERATIONS
POWER SUPPLY BYPASSING
Power supply pins are actually inputs and care must be taken so
that a noise-free stable dc voltage is applied. The purpose of
bypass capacitors is to create low impedances from the supply
to ground at all frequencies, thereby shunting or filtering most
of the noise.
Rev. E | Page 21 of 28
Decoupling schemes are designed to minimize the bypassing
impedance at all frequencies with a parallel combination of
capacitors. 0.1 μF (X7R or NPO) chip capacitors are critical
and should be as close as possible to the amplifier package.
The 4.7 μF tantalum capacitor is less critical for high frequency
bypassing, and, in most cases, only one is needed per board, at
the supply inputs.
GROUNDING
A ground plane layer is important in densely packed PC boards
to spread the current minimizing parasitic inductances.
However, an understanding of where the current flows in a
circuit is critical to implementing effective high speed circuit
design. The length of the current path is directly proportional to
the magnitude of parasitic inductances and therefore the high
frequency impedance of the path. High speed currents in an
inductive ground return will create an unwanted voltage noise.
