A package for circuit analysis in symbolic form with Mathematica

In this paper, a package for solving linear time-invariant analog electric circuits in Mathematica environment has been presented. The package uses the Mathematica´s powerful facilities to solve linear circuits with parametric elements. It consists of an Analysis module, a Tools module, a Graphs module, and an Utility module. All of the circuit responses such as node and element voltages and currents, network functions, and input/output impedance are available in the Laplace domain and in symbolic forms. The circuit responses to any signal sources defined by the user or signals obtained as an output of any system can be determined symbolically and graphically. Sensitivity analysis can also be performed on the specified expressions for variation of any parameters
