An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.   What is operational amplifier and its types? There are four ways to classify operational amplifiers:Current amplifiers receive a current input and produce a current output. Transconductance amplifiers convert a voltage input to a current output. Transresistance amplifiers convert a current input and produces a voltage output.   Where are operational amplifiers used? They are generally used to amplify weak electrical current in a circuit. Radios, stereo systems, headphones, TVs and many other electrical products include an operational amplifier as a component in many of their circuits.

The device can amplify analog or digital signals. It can also switch DC or function as an oscillator. Physically, a bipolar transistor amplifies current, but it can be connected in circuits designed to amplify voltage or power. What is the difference between a FET and a bipolar transistor?The acronym of the BJT is Bipolar Junction Transistor and FET stands for Field Effect Transistor. The major difference between BJT and FET is that in a field-effect transistor only majority charge carries flows, whereas in BJT both majority and minority charge carriers flow. What is BJT and its types?BJTs are of two types namely NPN and PNP based on doping types of the three main terminals. An NPN transistor consists of two semiconductor junctions that have a thin p-doped anode region and PNP transistor also consists of two semiconductor junctions that have a thin n- doped cathode region. Why BJT is called bipolar?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.

MOSFET transistor operation is based on the capacitor. This type of transistor is also known as an insulated-gate field-effect transistor (IGFET). What is Hexfet power Mosfet?The HEXFET®is fundamentally different: it is a voltage-controlled power MOSFET device. A voltage must be applied between the gate and source terminals to produce a flow of current in the drain (see Figure 1b). The gate is isolated electrically from the source by a layer of silicon dioxide. What is the use of N-channel MOSFET?The P-channel MOSFET is used to switch the positive supply to the motor for forward direction (high-side switching) while the N-channel MOSFET is used to switch the negative supply to the motor for reverse direction (low-side switching). How do you test an N-channel MOSFET?Hold the MosFet by the case or the tab but don't touch the metal parts of the test probes with any of the other MosFet's terminals until needed. First, touch the meter positive lead onto the MosFet's 'Gate'. Now move the positive probe to the 'Drain'. You should get a 'low' reading. What is the difference between MOSFET and power mosfet?Power MOSFET is a type of MOSFET which is specially meant to handle high levels of power. These exhibit high switching speed and can work much better in comparison with other normal MOSFETs in the case of low voltage levels. However its operating principle is similar to that of any other general MOSFET.
