CONTROLLED SOURCES1011303CONTROLLED SOURCESModels.When circuits containing electronic devices such as amplifiers and similar devices are analyzed or designed, it is necessary to have a linear circuit model for the electronic device. These devices have a minimum of three terminals. Currents flow between terminal pairs, and voltages appear across terminal pairs. One terminal may not be common to both pairs. A useful model is provided by a controlled source. Four such models may be distinguished, as shown in Fig. 2-25. Examples of use will appear in the paragraphs on circuit analysis.
