What is the difference between single stage and multi stage amplifiers?
single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage
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 transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
Difference between cascode and cascade amplifier?
cascade: the output of one amplifier stage is connected to the input of another amplifier stages, it's also connected in series. cascode: it said to be cascode, when it has one transistor on the top of another where a common emitter transistor drives a common base transistor.
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.
How should the two transistor junctions be biased for proper transistor amplifier operation?
Emitter-Base junction should be forward biased.Collector-Base junction should be reverse biased.
What is the advantage of two stage amplifier compared to single stage?
In a two stage amplifier the gain (ratio of the output to the input quantity) of the first stage is amplified again in the second stage so the gain of a two stage amp is the product of the gain of two individual stages which is sufficient enough to drive the output device as compared to a single stage amplifier.
How is negative feedback achieved in a single stage transistor amplifier?
A: Feedback is a signal fed back from the output like from collector to the base .
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.
What type of transistor is used in amplifier?
Depends on the type of amplifier. There are a lot of different circuits of amplifiers and each one of them use proper transistors, that works better for that circuit. Moreover, on every stage of the amplifier are used different transistors as well.
Working of RC coupled amplifier?
In a two stage RC coupled amplifier, the two transistors are identical and a common power supply is used. The input is provided to the first stage of the amplifier where it is amplified and this output is used as input for the second stage. This is amplied once again by the other transistor in the second stage and the final output is obtained. There will be a 180 degree phase shift after the first stage amplification which is nullified by the 180 degree phase shift of the second stage amplification.Thus, we obtain an output which is an amplified signal of the input and is in phase with the input signal.
What is the explanation for the working CE BJT amplifier?
In electronics, a common-emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies, typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input, the collector is the output, and the emitter is common to both (for example, it may be tied to ground reference or a power supply rail), hence its name.
