| Abstract: |
| This paper presents an analysis method, based on MacCormack's
technique, for the evaluation of the time domain sensitivity of
distributed parameter elements in high-speed circuit networks.
Sensitivities can be calculated from electrical and physical
parameters of the distributed parameter elements. The proposed
method is a direct numerical method of time-space discretization and
does not require complicated mathematical deductive process.
Therefore, it is very convenient to program this method. It can be
applied to sensitivity analysis of general transmission lines in
linear or nonlinear circuit networks. The proposed method is
second-order-accurate. Numerical experiment is presented to
demonstrate its accuracy and efficiency. |
