Experiment 1, Plotting Common- Emitter Characteristic Curves
Experiment 1, Plotting Common- Emitter Characteristic Curves For more courses visit show the basic method for Plotting Characteristic Curves of a typical NPN transistor give you experience working with the Common- Emitter (CE) amplifier configuration Common- Emitter Characteristic Curves show how a particular transistor type will react to variations in collector- Emitter voltage, collector current and base current. Once these variations are known, it is possible to develop a complete picture of how well a transistor will operate in a given amplifier design. In this Experiment , we will first look at the basic procedure followed to obtain a family of such Curves , and then see what our data actually tells us A typical set of Characteristic Curves is shown on the next slide. Such a group of lines is usually referred to as a family of Curves , because more than one line is drawn on the graph Each line shows how the collector current (IC) varies as the collector- Emitter voltage (VCE) is changed, while the base current (IB) is held constant The horizontal axis, of the graph, is divided into various values of VCE, while the vertical axis includes various values of IC Each line represents all possible combinations of VCE and IC for a particular value of base current Note that each curved line is marked with the base-current value.
