What are characteristic curves of a transistor?
The characteristic curves of a transistor provide the relationship between collector-emitter voltage and collector current for different values of the base current. Because there are two parameters that affect IC, a set of individual curves shown together denote various operating conditions.
What is the characteristic curve of BJT?
The collector characteristic curve shows the behavior of the transistor. To get these curves we bias a BJT transistor with a variable power supply and change the VBB and VCC. By variating these voltages, either transistor PN junctions may be forward or reverse biased.
What is the significance of the characteristic curve?
I-V characteristic curves are generally used as a tool to determine and understand the basic parameters of a component or device and which can also be used to mathematically model its behaviour within an electronic circuit.
What are the three types of configuration in transistors?
The three types of transistor circuit configurations are:
- Common Emitter Transistor.
- Common Base Transistor.
- Common Collector Transistor(emitter follower).
How do you characterize a transistor?
How to characterize a Transistor? : I-V Curve
- Horizontal Axis : Collector Emittor Voltage. It means the voltage measured across the transistor.
- Vertical Axis : Collector Current.
- Curve (Blue graph) : The relationship between Collector Emittor Voltage and Collector Current at a specific base current.
What are the different operating regions in a transistor output characteristics curve?
Transistor biasing Either forward or reverse biasing is done to the emitter and collector junctions of the transistor. These biasing methods make the transistor circuit to work in four kinds of regions such as Active region, Saturation region, Cutoff region and Inverse active region seldomused.
What is CE and CB configuration?
Generally there are three different configurations of transistors and they are common base (CB) configuration, common collector (CC) configuration and common emitter (CE) configuration. The behavior of these three different configurations of transistors with respect to gain is given below.
What are the characteristics of power transistor?
V-I Output Characteristics of a Power Transistor Voltage gain is high. The density of the current is high. The forward voltage is low. The gain of bandwidth is large.
