A common emitter BJT transistor has the emitter ground. So u measure input voltage at base with respect to the ground, i.e; emitter and also u measure the output voltage at collector with respect to the ground, i.e; emitter. Hence, the emitter is common and thus the name.

Which out of either the cccb or the ce configurations of a transistor is best and why?

The common emitter configuration works best because of the way the segments of transistors are biased, and the fact that there are more carriers in the collector than in the emitter.


Which transistor configuration has the highest input impedance?

Common Emitter Configuration has maximum impedance.


In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?

The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.


What are the three basic transistor connection configuration modes?

The three basic transistor connection configuration modes are common emitter, common base, and common collector. In the common emitter configuration, the emitter terminal is common to both the input and output circuits, providing high voltage gain. The common base configuration has the base terminal common to both circuits, offering high frequency response but low voltage gain. Finally, the common collector configuration, also known as an emitter follower, provides current gain and high input impedance while maintaining unity voltage gain.


What is the relationship between common base and common collector?

It all depends which lead is connected to the common power supply, Emitter, base or collector. For most amplification needs using NPN transistors, common emitter is used. Other applications are used for current control and regulation circuits.


Why biasing is needed at all?

Biasing is used in a transistor amplifier circuit in order to place the transistor as nearly as possible in the center of its linear region. Transistors have cutoff, linear, and saturation regions. Too little bias current, and you enter cutoff - Too much, and you saturate. Both conditions cause distortion when you attempt to use the transistor as an amplifier, as opposed to a switch.

What does it mean when you say a transistors junction is saturated?

It's called saturation because the collector voltage cannot go any lower. You've done all you can do with your base current (in Common Emitter configuration) to lower the collector voltage and support the collector current.
