Transient Analysis of Circuits Including
Frequency-Dependent Components Using
Transgyrator and Convolution
Frequency-domain characteristics,such as dispersion and frequency-dependent losses,affect the behaviour of a circuit strongly.The method we intend to present here is based on the partition of a circuit into a linear and a nonlinear part in a way similar to that used in the harmonic balance technique (see Fig.1).In the implementation of this method that has been done for the APLAC circuit simulation software the separation of the circuit is done by the user.The nonlinear part should contain components that have a time-domain model.The linear part should contain all components that are defined in the
frequency domain,i.e.,that have a frequency-domain model.Although time-domain
models exist for many frequency-dependent components,such as microstrips and
coupled line pairs,these models mostly cannot take frequency-domain characteristics
accurately into account.Therefore,in order to obtain an accurate representation
of these components,this method uses the frequency-domain models directly and
based on these creates an equivalent time-domain representation that contains the
frequency-domain characteristics.The linear part forms an n-port,for which we
intend to present an accurate time-domain representation.This is done by using
the Fourier transform to obtain the impulse response functions that represent the
y-parameters of the n-port in the time domain.
The input voltage pulse is shown in Fig.11.Although there is only one source,
we should expect the coupling between the microstrip lines to cause some voltage
waveform at both loads.As explained above,Mclin allows us to verify our results
(as long as no frequency-domain characteristics are taken into account) with normal
transient analysis.The results are,as expected,exactly the same.Fig.12 shows the
voltage waveforms at the coupled line load,obtained by normal transient analysis
and by transient analysis using convolution.Both graphs are identical (they coincide,
as can be seen from the markers).When the frequency-domain characteristics
are taken into account,which means that the y-parameters obtained for the n-port
used in our method are affected by dispersion and frequency-dependent losses,the
results change noticeably.Since the Mclin frequency-domain model is capable of
taking into account all the frequency-domain characteristics in an AC analysis,we
are able to obtain the y-parameters that we need through consequent AC analyses
at different frequencies using APLAC.The result presented in Fig.13 shows that
the coupled line load voltage waveform clearly becomes more \rounded" and that
its amplitude decreases when the frequency-domain characteristics are taken into
account.This could be expected,since at higher frequencies we are confronted with
larger losses.Dispersion affects the waveform so that it becomes smoother.
