What else can I help you with?
Am amplifier that inverts the signal between input and output is called a what?
common emitter
What is amplifier and what is the general circuit of amplifier?
An amplifier amplifies voltage or current. The most basic amplifier consists of a transistor where a signal is fed into the base and is output to the emitter or collector. For simple, low frequency applications (not RF), it may be simpler to use an operational amplifier (op amp) than designing your own amplifier. Also, the data sheets provide very helpful schematics for creating an amplifier. A very common one is the 741; these are also fairly cheap.
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.
What is one common application of a cc amplifier?
current amplifier
What is the function of emitter bypass capacitor in common emitter amplifier?
The emitter bypass capacitor in a common emitter amplifier will have less resistance as the frequency increases. Since gain in this configuration is collector resistance divided by emitter resistance (within limits of hFe), the gain will thus increase for higher frequencies, making this into a high pass filter.
Application of a common - collector amplifier circuit?
Common collector amplifier can be used as a voltage buffer and in impedance matching
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
What is the formula for VE in a common collector amplifier?
what is common collector
What is the other name for the common-collector amplifier?
emitter follwer
what is the Primary function of the common collector amplifier?
current gain
Why is a common collector used in the last stage of the amplifier?
becoz it gives good gain which is necessary for an amplifier.
Main use of a Common collector transistor amplifier is?
No voltage gain
What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
What is the applications of bootstrap amplifier?
it is a mechanism applied in an amplifier so as to raise it's input impedance.Mostly this mechanism is applied in a common collector(emitter follower) amplifier.
Why is common emitter is greater than common collector?
Common-emitter gives more voltage gain because a common-collector amplifier has a voltage gain of 1. But a common-collector can have a power gain because the input impedance is much more than the output impedance.
Why is it the phase relationship between input and output signals of the common collector amplifier is in phase?
no phase shift
Why in common collector amplifier however you change value of resistance not amplifier in voltage?
The question does not quite make sense. It sounds like you are asking why does changing the emitter resistor in a class C common collector amplifier not affect the output voltage? If so, the answer is that the common collector is an emitter follower, meaning that the emitter will follow the base, less the base-emitter junction voltage, within the limits of hFe. The resistor is simply there to ensure output biasing when the base voltage goes low.
