6 Intermodulation Distortion Product
The non-ideal output of the amplifier can be described by the following series:
due to non-linearity in the input-output amplitude transfer, where the input is V

ω
t, C
0
is the DC
component, C
1
(V
in
) is the fundamental and C
n
is the amplitude of the harmonics of the output signal V
out
.
A one-frequency (one-tone) input signal contributes to harmonic distortion. A two-tone input signal
contributes to harmonic distortion and to the intermodulation product.
The study of the intermodulation and distortion for a two-tone input signal is the first step in characterizing
the driving capability of multi-tone input signals.
In this case:
then:
From this expression, we can extract the distortion terms, and the intermodulation terms form a single
sine wave: second order intermodulation terms IM2 by the frequencies (

and third order intermodulation terms IM3 by the frequencies (2

) and (

) with an amplitude of (3/4)C3A

.
The measurement of the intermodulation product of the driver is achieved by using the driver as a mixer
by a summing amplifier configuration (see
Figure 33
). In this way, the non-linearity problem of an external
mixing device is avoided.
