Common emitter active region
WebJul 12, 2024 · 1 First, let's look at the standard common-emitter circuit. There's two ways to look at this We can keep I b constant and increase R C or decrease V c c until the transistor enters saturation. In this case, the collector current is minimum at saturation, or anyway less than it was when we were operating the BJT forward-active. WebThe configuration in which the emitter is connected between the collector and base is known as a common emitter configuration. Common Emitter (CE) Configuration of Transistor The transistor characteristic under Common Emitter configuration is as follows: Common Base (CB) Configuration of Transistor

WebApr 8, 2024 · The active region of the Transistor is the area on the Output curve where the Output Current is almost constant and independent of the Output Voltage. The Transistor operates in the Active region if the base resistance is greater than the maximum value allowed. A Transistor can only be used as an amplifier if it is in the active region.
