The dual of Thevenin, Norton equivalent circuit is used in place of any circuit/network of linear sources and immittances at at a given frequency. Both Thevenin with Norton theorem is useful for analyses and modification of circuits, to study /obtain network’s steady state response and initial condition. Methods to represent different circuits with Thevenin/Norton impedances connected at desired nodes are given using Spice/Pspice. The Thevenin/Norton impedances connected are of other networks which are independent with non-linear elements (diode etc). The Thevenin/Norton impedances are scaled to the desired level after obtaining small –signal equivalents for non-linear elements (diode).    Circuit analyses and simulation methods with SPICE /OrCAD software to obtain Norton and Thevenin equivalent circuits for networks containing non-linear elements such as diodes are described to simulate other different networks with scalar multiples of previous equivalent circuit parameters (Thevenin and Norton). Using Spice/Pspice simulator the non-linear circuit is described in two ways, (I) to obtain Thevenin open circuit voltage(ac), (ii) to obtain AC Thevenin without changing DC bias of non-linear element. Here, the individual parameters are from a different circuit (Thevenin/Norton equivalents) are implemented in other networks.

Keywords: Analog network theory, non- linear circuits, complex variables, circuit simulation and modelling, rf and microwave circuits, computer aided design
