Why CE mode amplifier is preferred over CB and CC?

CE gives high gain and amplification as compared to CB and CC. That's why its preferred. input and output resistance moderate value,so many stages coupled to each other without using any additional impedence matching circuit.so maximum power transfer takes place from one stage to another. THAT'S why it is preffered.


What two stages does the Darlington Pair consist of 1 CE CC 2 CE CB 3 both CE 4 D both CC?

CE and CB


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.


How do you calculate h parameters in CE and CB configurations?

You can calculate h parameters in CE and CB configurations by the diagram that you are looking at, but if need be there are a few formulas you can use.


Why power amplifier are called as large signal amplifiers?

in general the CE amplifiers are called low-signal amplifiers as they use only small values of voltage as a source of input which cant be used in practical purposes, whereas power amplifiers deal with practical values of input and output voltages


Which configuration gives no current gain?

cc/ce/cb doesn't give the no current gain


What is Current amplification factor in common emitter configuration?

comparerission between CB,CC&CE


Which transistor configuration has the highest voltage gain?

Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).


Why CE transistor is more temperature senstive than CB transistor?

In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.


Why does ce configuration provide large current amplification while the cb configuration does not?

The common emitter (CE) configuration provides large current amplification because it utilizes a small base current to control a much larger collector current, resulting in a significant current gain (β). In contrast, the common base (CB) configuration does not offer the same level of amplification since it is designed for high-frequency applications and has a lower input impedance, which leads to a smaller output current relative to the input. Additionally, the CB configuration does not allow for the same degree of control over the collector current by the base current as the CE configuration does.


What is the difference between a CB amplifier and CE and emitter-follower?

I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.


What are typical values of input impedance and outoput impedance of ce amplifiers?

Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
