What is the difference between bipolar and unipolar transistors?
A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. Hundreds of bipolar junction transistors can be made in one circuit at very low cost.
What is the difference between field effect transistor and Mosfet?
JFET(Junction Gate Field-Effect Transistor) is a three-terminal semiconductor device. MOSFET(Metal–Oxide–Semiconductor Field-Effect Transistor) is a four-terminal semiconductor device. It can only operates in the depletion mode. It operates in both depletion mode and enhancement mode.
What is field effect transistor?
The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. FETs are devices with three terminals: source, gate, and drain. Field effect transistors generally display very high input impedance at low frequencies.
What is a bipolar transistor?
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 the difference between a BJT and a field effect transistor?
BJT is bipolar (Current flows due to both electron and hole carriers) and Field effect transistor (FET) is unipolar (Current flows due to majority carrier i.e. Electron for N-type FET and hole for P-type FET). BJT is a current controlled device but Field effect transistor is a voltage controlled device.
What is the difference between bipolar junction transistor and NPN transistor?
In NPN, electrons are dominant and holes are less. In PNP Holes are dominant and electrons are less FET Current depends upon Gate to Source Voltage and hence known as Voltage controlled device FET input impedance is more than BJT.

What are the applications of bipolar transistors?
The applications of BJTs involve a wide range that includes electronic devices like TVs, mobiles, computers, radio transmitters, audio amplifiers, and industrial control. A bipolar junction transistor comprises two p-n junctions. Depending on the structure of the BJT, these are classified into two types such as PNP and NPN.
Is a bipolar junction transistor (BJT) device a transducer in electrochemical sensor?
Recently, bipolar junction transistor (BJT) device 16, 17, 18 was proposed as a transducer in an electrochemical sensor. In this study, we compare a FET transducer with the recently proposed BJT transducer. The objective is to evaluate the impact of the transducer type on the performance metrics of an electrochemical sensor.
