Bjt in saturation region
Indeed, if you increase the amplitude of the input signal, the BJT will first enter the saturation region and then the breakdown region. In the saturation region the output signal is highly distorted. In the breakdown region, if the base current becomes large enough, the BJT dies of a horrible albeit quick death.(Saturation region) 5 70 60 PA 50 PA 40 30 (Active region) 20 10 PA 20 (Cutoff region) Ic ('ITA) (Saturation region) 5 70 60 PA 50 PA 40 30 (Active region) 20 10 PA 20 (Cutoff region) Title: Slide 1 Author: David L.

ASSUME it is in active mode and ENFORCE V Saturation Region is also primarily used in switching 81. A transistor goes into saturation when both the base-emitter and base-collector junctions are forward biased, basically. So if the collector voltage drops below the base voltage, and the emitter voltage is below the base voltage, then the transistor is in saturation. Consider this Common Emitter Amplifier circuit.The Bipolar Junction Transistor (BJT) as a Switch; Meter Check of a Transistor (BJT) Active-mode Operation (BJT) The Common-emitter Amplifier; ... the transistor will “throttle” the collector current in a mode somewhere between cutoff and saturation.

14. There is a precise definition and a sloppy one for saturation. I'll start with the precise one. That's pretty much it. The saturation region is precisely defined here. The sloppy one comes about because the practical behavior of different parameters of the BJT don't all neatly fall so perfectly on those lines.BJT Regions of Operation To understand the three regions of operation of the transistor, consider the circuit below: Vin R1 + 10K R2 1K Q1 Vbe - Vout 10V - The first region is …Yes, and this is why the region of Vce<0.7 is the saturation region. But, the transistor equations say that the current in a forward biased junction is exponentially related to the voltage. So, very little forward bias current is flowing if Vce=0.6 V, as this is only a 0.1 V forward bias. Let's run some typical numbers for a silicon diode.
