What are disadvantages of transistors?
(1) It is sensitive to temperature, (2) It produced very low energy. (3) The power transistor cannot be operating satisfactorily above the switching frequency of 15 kHz.
What are the advantages and disadvantages of FET over BJT?
FETs are more temperature stable than BJTs. FETs are generally easier to fabricate than BJTs. Greater numbers of devices can be fabricated on a single chip (i.e., increased packing density is possible). FETs react like voltage-controlled variable resistors for small values of drain-to-source voltage.

Advantages and Disadvantages of Transistors
Advantages | Disadvantages |
---|---|
Low source voltage | Temperature dependency |
High voltage gain | Lower power dissipation |
Smaller in size | Low input impedance |
What are the disadvantages of Mosfet over BJT?
Lower Input Power Loss MOSFET has lower input power loss than a BJT. The equivalent input power loss of the BJT is the sum of the input capacitance and the VBE losses. The former is just a small portion compared to the latter. The power loss due to VBE is the product of the base current and the VBE voltage.
What are the drawbacks of a transistor voltmeter?
VTVM cannot measure current directly because of its high resistance whereas TVM can do. TVM consumes very less power because of absence of heating element. The only disadvantage with TVM is low input impedance which it offers in comparison to VTVM.
What are the disadvantages of junction field effect transistor?
The main disadvantage of the junction field-effect transistor (JFET) is the relatively low gain-bandwidth product. The performance of JFET goes down as frequency increases due to feedback by internal capacitance.
What is NPN bipolar junction transistor?
NPN transistors are a type of bipolar transistor with three layers that are used for signal amplification. It is a device that is controlled by the current. A negative-positive-negative transistor is denoted by the abbreviation NPN. In an NPN transistor, the flow of electrons is what causes it to conduct.
What is the disadvantage of integrated circuit *?
What is the disadvantage of integrated circuit? Explanation: The disadvantage of IC is that, a lack of flexibility an IC. It is generally not possible to modify the parameters within which an integrated circuit will operate.
What are the advantages of MOSFET with bipolar junction transistor?
Mosfet provides a very good isolation between the gate and the other two terminals compared to bjt. MOSFET can handle more power compared to BJT. The mosfet has a very low power loss and a high speed. Voltage signals can easily operate a mosfet, so it is used in many digital circuits.
Why BJT is bipolar device?
Bipolar transistors are a type of transistor composed of pn junctions, which are also called bipolar junction transistors (BJTs). Whereas a field-effect transistor is a unipolar device, a bipolar transistor is so named because its operation involves two kinds of charge carriers, holes and electrons.
What is a BJT transistor?
A bipolar junction transistor (BJT) is a type of semiconductor that uses both electron and hole charge carriers. They are used to amplify electric current. BJTs are available both alone or packaged into integrated circuits (ICs). BJTs are widely used in amplifiers for a large amount of everyday electronic equipment.
What is VBE of a transistor?
VBE is the voltage that falls between the base and emitter of a bipolar junction transistor. VBE is approximately 0.7V for a silicon transistor. For a germanium transistor (which is more rare), VBE is approximately 0.3V.
What is a bipolar junction transistor?
A bipolar junction transistor is also known as a bipolar transistor. A bipolar junction transistor is a type of semiconductor that is formed by joining two types of semiconductors, P-type and N-type, with a third base. This base can modulate the amount of electricity flowing through it.
