Transistor

This Area Cover topics about Transistor and its uses. Main Topics to cover all transistor related practical issue and its solution, its also cover different type of usage of Transistor in circuit.

What is the difference between a transistor and a variable resistor?

What is the difference between a transistor and a variable resistor? A resistor is considered a passive device and has two connections and a nominal fixed resistor. A transistor is considered an active device and has three connections. A terminal…

Can transistors replace capacitors and resistors

Can transistors replace capacitors and resistors? It is done on IC very currently. The resistance is easy with the fets and the capacitor really cannot be totally replaced, it can be multiplied thus making the small capacity bigger and useful.…

What is the difference between a resistor and a transistor?

Here we discuss Difference between a resistor and a transistor in very short. Transistor means resistance transfer, so its name makes the difference with resistance. The transistor is a 3-terminal active element. It can work in 3 regions. 1) active…

difference between NMOS PMOS and CMOS transistors

NMOS is constructed with the n-type source and drain and a p-type substrate, while PMOS is constructed with the p-type source and drain and an n-type substrate. In an NMOS, carriers are electrons, while in a PMOS carrier are holes.…

Which are the best transistors CE CB or CC

Which are the best transistors CE CB or CC? The transistors are the best because they provide you with a high gain voltage output and a high input impedance. These are used in amplification processes. The transistors have an input…

Why transistor is so difficult to understand

Why transistor is so difficult to understand? intuition of the operation of a bjt is more difficult than the intuition of a mosfet but the equations of the model of a bjt are much simpler than those of the model…

Does a transistor amplify current or voltage

transistor is a current-controlled device. current amplification only in common basic mode, only voltage amplification occurs, in common collector mode, only current amplification occurs, in common emitter mode, amplification of voltage and current occurs. Does a transistor amplify current or…

Can transistors work with ac

Can transistors work with ac? Yes. the exact function depends on how you connect the transistor. in addition, the frequency changes the gain of the transistor. use a power bjt for high voltages. The standard transistors are supposed to conduct…

Why are PNP transistors used

Why are PNP transistors used? We use pnp mainly for convenience and to simplify certain circuits. npn is a device used to reduce current, while pnp is a device used to find power. for a current source, it is clear…

What is a Q point of a transistor

Q point of a transistor? The point q of a circuit describes the output level when the input is short-circuited or disconnected. that is to say that the transistor (s) of the circuit is (are) controlled solely by the polarization…

Why do we use biasing in transistor

The polarization of the transistor is to switch the glass, which facilitates the passage of the current from the source to the drain, or from the transmitter to the collector. that’s why we use the term “polarization”. we want to…

Why are transistors called transistors

Why are transistors called transistors? it is nothing more than a semiconductor device through which currents and voltages of the desired magnitude can be obtained. It can be used as a switch as well as an amplifier. it makes it…

What controls the gate in a transistor

What controls the gate in a transistor? inside a microchip, transistor gates are usually driven by other transistors but they could also be driven by transistors directly or directly connected to other elements such as resistors and capacitors. the transistors…
