Most resistors generate noise due to the passage of
current through the resistor. This noise is dependent
on the amount of current, the resistive material and
the physical construction of the resistor. The
physical construction is partly influenced by the laser

Resistors in general are designed to function
according to ohmic laws. This is basically true of
rectangular chip resistors for frequencies up to 100
kHz. At higher frequencies, the capacitance of the
terminations and the inductance of the resistive path
length begin to have an effect.
Basically, chip resistors can be represented by an
ideal resistor switched in series with a coil and both
switched parallel to a capacitor. The values of the
capacitance and inductance are mainly determined by
the dimensions of the terminations and the
conductive path length. The trimming pattern has a
negligible influence on the inductance, as the path
length is not influenced. Also, its influence on the
capacitance is negligible as the total capacitance is
largely determined by the terminations.
