Slightly less than cc configuration but greater than cb
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.

Common emitter is the preferred circuit because the collector voltage drops to a well defined low value when the transistor is 'on', therefore it absorbs only a small amount of power.
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.
the CB configutration is having low impedance & hence used in I-V converters(current -voltage converters)
Slightly less than cc configuration but greater than cb
cc/ce/cb doesn't give the no current gain

In a Common Base (CB) configuration, the input terminal is the emitter, where the input signal is applied, and the output terminal is the collector, where the output signal is taken. The base terminal is common to both the input and output circuits, hence the name "common base." This configuration is known for providing high-frequency response and low input impedance.
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
depends if you want standard velocity cb or sub sonic. the most common cb is the CCI sub sonic cb. cb stands for conical ball
