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 does vcc voltage called vcc?
I believe that Vcc stands for Voltage Common Collector. This is because the voltage is hooked up to the collector of the transistor.
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
Why we kept VOLTAGE collector to emitter half of voltage vcc?
We bias the common emitter amplifier to have a collector-emitter voltage of one half of Vcc in order to set the operating point halfway between the two extremes.
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.
Main use of a Common collector transistor amplifier is?
No voltage gain
Common collector amplifier does not have voltage gain but still provide power gain?
It still has a current gain significantly high though the voltage gain is close to unity.
What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
What is the Frequency response of common emitter amplifier?
The voltage gain is a measure of the amplified output available at the collector terminal divided by the voltage measured on the base. This if you have 10 mV applied to the base and voltage of 1 volt at the collector the voltage gain is 100ANSWERThe maximum voltage gain of a common emitter amplifier is dependant on the transistor itself. Some have only a very small voltage gain such as in Radio Frequency Power transistors. These are almost all used as common emitter circuits for bipolar transistors or common source for FETs.. On the other hand some darlington transistors can have common emitter gains of hundreds of thousands. If the stage has an unbypassed emitter resistor, the voltage gain is equal to Rload/RE, (Rload is the parallel value of the resistance from collector to the supply and the resistance of the load).If the emitter resistance is bypassed, the value of resistance to be used for RE is the internal Re which is equal to 25mV/Ie
Why does vcc voltage called vcc?
I believe that Vcc stands for Voltage Common Collector. This is because the voltage is hooked up to the collector of the transistor.
Can you use CC configuration as an amplifier?
The Common Collector configuration amplifies current, by having the emitter voltage follow the base voltage, with an offset of the forward conduction voltage of about 0.7 volts, with a current gain of beta. (hFe)
Application of a common - collector amplifier circuit?
Common collector amplifier can be used as a voltage buffer and in impedance matching
What are common uses of a common emitter amplifier?
bcause amplification factor beta is usually ranges from 20-500 hence this configuration gives appericiable current gain as well as voltage gain at its output on the other hand in the Common Collector configuration has very high input resistance(~750 kilo ohm) & very low output resistance(~25 ohm) so the voltage gain is always less than one & its most important application is for impedance matching for drivingh from low impedance load to high impedance source
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
what is the Primary function of the common collector amplifier?
current gain
