What are characteristics of BJT?
BIPOLAR JUNCTION TRANSISTOR CHARACTERISTICS
- Active region: In this region, the base emitter junction is forward biased and the base-collector junction is reverse biased.
- Cut-off region: In this region, both base-emitter and base-collector junctions are reverse biased and the transistor acts like an open switch.
What are transistor characteristics?
In physics, the graph representing the relationships between the current and the voltage of any transistor of any configuration is called Transistor Characteristics. Any two-port network which is analogous to transistor configuration circuits can be analyzed using three types of characteristic curves.

How do BJT transistors work?
A BJT is a type of transistor that uses both electrons and holes as charge carriers. A signal of small amplitude if applied to the base is available in the amplified form at the collector of the transistor. This is the amplification provided by the BJT.
What is the difference between BJT and NPN Transister?
An NPN transistor has a layer of P-doped semiconductor between two N-doped layers (Courtesy of Wikibooks) Cutoff: BJT operates in this zone in switching operations. In cutoff, the transistor is inactive. Active: BJT operates in this zone for amplifier circuits because the transistor can act as a fairly linear amplifier.
What are advantages of a BJT amplifier?
They have a better voltage gain
How is MOSFET different from BJT?
Difference between BJT and MOSFET. The BJT is a bipolar junction transistor whereas MOSFET is a metal oxide semiconductor field effect transistor. A BJT has three terminals namely base, emitter and collector, while a MOSFET has three terminals namely source, drain and gate.
What are transfer characteristics of a BJT?
The BJT Transfer Characteristic This ratio is the CURRENT GAIN of the transistor and is given the symbol h fe. A fairly low gain transistor might have a current gain of 20 to 50 , while a high gain type may have a gain of 300 to 800 or more.
