WebI created the following circuit using a npn transistor. simulate this circuit – Schematic created using CircuitLab. After measuring all the voltages, I got: \$ V_{BE}\approx 0.6V, V_{CB}>0 \$. Are those measurements sufficient to say that the transistor is operating in the active region? How can I prove it theoretically? WebThere are different types of transistor amplifiers operated by using an AC signal input. This is interchanged between the positive value and negative value, hence this is the one way of presenting the common emitter amplifier circuit to function between two peak values. This process is known as the biasing amplifier and it is an important amplifier design to …

WebQuestion 11. Many technical references will tell you that bipolar junction transistors (BJTs) are current-controlled devices: collector current is controlled by base current. This concept is reinforced by the notion of “beta” (β), the ratio between collector current and base current: β = I C I B β = I C I B.
