What is the difference between active and saturation region?

What is the difference between active and saturation region?

a)When both collector-base & base-emitter junction is reverse biased, it is the active region. b)When both collector-base & base-emitter junction is forward biased, it is the saturation region.

What is active region of a transistor?

Active region is that region in which emitter base junction is forward bias while collector base junction is also forward bias.

What is saturated region in transistor?

In cutoff, the transistor appears as an open circuit between the collector and emitter terminals. In the circuit above, this implies Vout is equal to 10 volts. The second region is called “saturation”. This is where the base current has increased well beyond the point that the emitter-base junction is forward biased.

What is the saturation region?

Saturation region This is the region in which transistor tends to behave as a closed switch. The transistor has the effect of its collector and Emitter being shorted. The collector and Emitter currents are maximum in this mode of operation. The figure below shows a transistor working in saturation region.

How do you tell if a transistor is saturated?

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.

What is saturation region?

The Saturation Region of a FET transistor is the region where the drain current, ID, flowing from the drain to the source of the FET transistor, is the highest for the gate-source voltage, VGS, that is supplied.

What is saturation region in BJT?

The saturation region of a MOSFET is similar to the active region of a BJT (load current doesn’t change much with a change in voltage). The definition of BJT saturation is that the magnitude of the collector-emitter voltage ( Vce ) is equal to or less than the magnitude of the base-emitter voltage (Vbe).

What is the active region of a transistor?

Active Region of a Transistor. The Active Region of a transistor is the region where the transistor is on and is receiving sufficient base current for collector current to conduct. Basically, this is the region where the transistor is on and current conducts across the collector.

What is cutoff region in transistor?

Cutoff Region of a Transistor. The Cutoff Region of a transistor is the region where there is no collector current because the base current going into the transistor is too small.
