generally CE amplifier is considered as the most common amplifier because of two reasons :-
1. it has a good current gain (almost >100) :- this is eslf -explainable as more the output more willingly it would be used as an amplifier
2. low input current :- this is the most important reason , if we recall the input current in CE configuration we will come to know that it is the base current . base current has less magnitude this helps the designer to control it easily when compared to higher order magnitude currents like collector and emitter current as
What else can I help you with?
Why CB amplifier preferred for high frequency than CE amplifier?
1)in cc configuration we use to get the low output impedence where as in ce we use to get the high output impedence. 2)in cc amplifier we use to have the voltage gain equal to unity where as in ce amplifier we use to have the high voltage gain. 3)in cc amplifier there is high power gai which is used for impedence matching where as in ce amplifier due to the high voltage gain the impedence matching is less impossible.
What is the common transistor configuration used for signal amplifier?
Class A amplifiers for signals and class AB for power output. The bias is often set up as a self biased amp.
How output voltage is out of phase in CE?
It should be ~180 degrees out of phase, because a CE amplifier is an inverter. A BJT CE amplifier is a good example to look at. The output is across CE, and at a minimum total output voltage is split across CE and some resistor R. As a higher voltage is applied to the base, the current flow through CE increases as a result of the resistance of CE decreasing. This boils down to a simple voltage divider at the output, Vout = CE / (R + CE). As CE decreases as a result of the input increasing, Vout will decrease.

What is Ce amplifier?

Why ce configuration of transistor has a 180 phrase difference in output?
A: As current begins to flow the action on a resistance will be a voltage drop which is inversely proportional to the current. Making it a voltage amplifier as opposed to a tube where it is a current amplifier

What is the difference between cb and ce configuration of a npn bjt?
Both configuration works as amplifire, yet with following charactristics.1. CB configNon inverting amplifierCurrent gain is always less than unityVoltage gain can be high, which is function of output and input impedance.Ic/Ie is always less than unity2. CE config Inverting amplifierTypically used as voltage amplifier since it can have large voltage gainModerate current gain

Class A amplifiers for signals and class AB for power output. The bias is often set up as a self biased amp.
Why is the gain and bandwidth of a ce-cb cascode amplifier greater than a ce amplifier?
Gain of ce-cb cascode is nearly equal to the gain of ce amplifier, because in a ce-cb cascode, the gain of the ce stage is equal to 1, and the gain of the cb stage is nearly equal to an isolated ce amplifier. Hence, gain of both are nearly equal. On the other hand, Bandwidth of ce-cb cascode is much higher than the bandwidth of ce amplifier because the cb stage in the cascode configration is not subjected to any Miller effect, thereby improving the high frequency response. The absence of Miller effect is due to the fact that the base of the cb stage is grounded thus, shielding the collector signal from being fed back into the emitter input. To be more clear, the gain of CE stage in cascode is nearly 1, which reduces the miller effect on the cb stage greatly.
Which transistor configuration has the highest voltage gain?
Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).
Why phase shift of ce configuration is 180 out of phase while cc has same phase?
In a ce amplifier, an increase of base voltage causes the collector current to rise. This causes an increased voltage drop through the collector load resistor, so the collector voltage drops. With a cc amplifier the increase in current causes more voltage across the emitter load resistor, therefore the emitter voltage rises.
