Application Information
POWER LINE NOISE FILTERING
A factor to consider in designing power and ground is noise
filtering. A noise filtering circuit is designed to prevent noise
generated by the integrated circuit (IC) as well as noise
entering the IC from other devices. A common filtering
method is to place by-pass capacitors (C
bp
) between the
power and ground lines.
Placing a by-pass capacitor (C
bp
) with the correct value at
the proper location solves many power supply noise prob-
lems. Choosing the correct capacitor value is based upon
the desired noise filtering range. Since capacitors are not
ideal, they may act more like inductors or resistors over a
specific frequency range. Thus, many times two by-pass
capacitors may be used to filter a wider bandwidth of noise.
It is highly recommended to place a larger capacitor, such as
10μF, between power supply pin and ground to filter out low
frequencies and a 0.1μF to filter out higher frequencies.
By-pass capacitors must be mounted as close as possible to
the IC to be effective. Long leads produce higher impedance
at higher frequencies due to stray inductance. Thus, this will
reduce the by-pass capacitor’s effectiveness. Surface
mounting chip capacitors are the best solution because they
have lower inductance.
