A Novel Method Towards Time-Efficient Fault Analysis of Analog and Mixed-Signal Circuits

摘要

A novel method of nodal impedance calculation is presented in this paper. This method is capable of time-efficient calculation of arbitrary two-point complex impedance in an analog and mixed-signal circuit and could improve the development time of impedance-based tests both in DC and AC domain. A fault simulation methodology based on the proposed method is described in detail. Several experiments are provided that prove the time efficiency of the method. Experimental application showing the benefits of the method on a real circuit is provided as well.
