This paper presents a new methodology for obtaining all the operating points in piecewise-linear (PWL) electrical networks. The networks can include independent and controlled voltage or current sources, resistors or conductances, and PWL elements. The nonlinear behavior of the PWL elements is graphically described by one-dimensional PWL curves. The(More)
A MAPLE-based package for detecting feedback loops -positive and negative - has been developed. The tool accepts the circuit description either through a SPICE-like input file or via a schematic editor. The method for finding feedback loops is based on a slightly modified version of the well-known LU decomposition algorithm. In the paper, the idea behind(More)
