When an n-p-n transistor is used as an amplifier, it operates in the active region, where a small input current at the base controls a larger output current flowing from the collector to the emitter. This configuration allows the transistor to amplify the input signal, producing a larger output signal that maintains the same phase. The transistor's ability to amplify is largely determined by its current gain (beta), which indicates how effectively it can control the output current based on the input current. Proper biasing is essential to ensure the transistor remains in the active region for linear amplification.
What else can I help you with?
Is a npn transistor a process or output?
An NPN transistor is a type of semiconductor device, specifically a bipolar junction transistor, and is not classified as a process or output. It serves as a fundamental building block in electronic circuits, functioning as a switch or amplifier. In this context, it can control current flow and signal amplification, but it itself is not a process or output.
What is the function of resistor in single stage amplifier?
A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.
How do you design a RC coupled bjt amplifier using pnp transistor?
same as you would using an NPN, except the supply voltages are reversed
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
Why a transistor is called with BC547?
A small signal NPN transistor used for general purpose audio amplifiers and switching.
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
Why is npn transistor called emmitor follower?
In an NPN transistor an emiter follower refers to an amplifier topology. The emiter follower configuration is when the emitter of a N-Type Bipolar Junction Transistor (BJT) is connected to the common point on a circuit (typically ground). This is not always the case, however, because many amplifier configuration exist.
How transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.
