| description | In this contribution, a system identification procedure of a two-input Wiener
model suitable for the analysis of the disturbance behavior of integrated
nonlinear circuits is presented. The identified block model is comprised of
two linear dynamic and one static nonlinear block, which are determined using
an parameterized approach. In order to characterize the linear blocks, an
correlation analysis using a white noise input in combination with a model
reduction scheme is adopted. After having characterized the linear blocks,
from the output spectrum under single tone excitation at each input a linear
set of equations will be set up, whose solution gives the coefficients of the
nonlinear block. By this data based black box approach, the distortion
behavior of a nonlinear circuit under the influence of an interfering signal
at an arbitrary input port can be determined. Such an interfering signal can
be, for example, an electromagnetic interference signal which conductively
couples into the port of consideration. |
