Constructive homotopy methods for finding all or multiple DC operating points of nonlinear circuits and systems

This paper develops a constructive homotopy-based methodology for finding all or multiple dc operating points of nonlinear circuits and systems. Several sufficient conditions for the connectivity of all the solutions along a single homotopy path are derived. These conditions offer criteria to determine an initial guess from which all the solutions can be obtained by following the single homotop...

A Method for Multiple Fault Diagnosis in Analog Circuits

---Fault diagnosis of analog circuits is essential for analog and mixed-signal circuits testing and maintenance. In this paper, a new method for multiple fault diagnosis in linear analog circuits is proposed based on the large change sensitivity analysis and ambiguity group locating technique. Test equation establishes the relationship between the measured responses and deviations of faulty par...

DC operating points of transistor circuits

Finding a circuit’s dc operating points is an essential step in its design and involves solving systems of nonlinear algebraic equations. Of particular research and practical interests are dc analysis and simulation of electronic circuits consisting of bipolar junction and fieldeffect transistors (BJTs and FETs), which are building blocks of modern electronic circuits. In this paper, we survey ...
