Types of Transistors

 What are Transistors Configurations?

Generally, there are three kinds of configurations, and their descriptions with recognition to gain are as follows:

Common Base (CB) Configuration: It has no present-day benefit but has a voltage advantage.

Common Collector (CC) Configuration: It has contemporary benefits but no voltage advantage.

Common Emitter (CE) Configuration has present-day benefits and voltage advantages.

Transistor Common Base (CB) Configuration:

In this circuit, the base is not unusual for entering and outputting. It has a low enter impedance (50-500 ohms). On the other hand, it has high output resistance (1-10 mega ohms)—voltages measured with appreciation to base terminals. So, enter voltage and cutting-edge could be Vbe & Ie, and the output voltage and current will be Vcb & Ic.

Current Gain could be less than team spirit, i.E., alpha(dc)= Ic/Ie

Voltage gain might be high.

Power advantage could be shared.

Transistor Common Emitter (CE) Configuration:

In this circuit, the emitter is not unusual for each input and output. The enter signal is implemented between the base and emitter, and the output signal is executed between the collector and emitter. Vbb & Vcc are the voltages. It has excessive input impedance i.E., (500-5000 ohms). On the other hand, it has low output resistance i.E., (50-500 kilo ohms).

Current Gain could be excessive(ninety eight) i.E., beta(dc) =Ic/Ie

The power advantage is up to 37db.

Output could be a hundred and eighty levels out of phase.

Transistor Common Collector Configuration:

In this circuit, the collector is not unusual for each entry and output. This is likewise called emitter follower. It has excessive input impedance (150-600 kilo ohms). On the other hand, it has a low output impedance(one hundred-a thousand ohms).

The current advantage could be excessive(ninety-nine).

Voltage benefit will be much less than solidarity.

Power gain could be shared.

Field Effect Transistor (FET):

Field Effect Transistor contains three areas: a supply, gate, and drain. They are termed voltage-managed devices as they manipulate the level of voltage. The externally implemented electric subject can be chosen to manage the electrical conductivity. That’s why they referred to them as field impact transistors. In this, the present-day flows because of majority price carriers, i.E., electrons, for this reason, also called the uni-polar transistor. It typically has high input impedance in mega ohms with low-frequency conductivity between the drain and source managed utilizing the electric subject. FETs are notably green, lively & lesser in cost.

Field effect transistors are of two sorts, i.E., Junction area effect transistors (JFET) and Metal oxide area effect transistors (MOSFET). The modern passes between the two channels are named n-network and p-channel.
