why common emitter configuration is used more than common base configuration of transistor for amplification purpose? when common base configuration provides more stability than of common emitter configuration
Common collector: Current gain but no voltage gain
Common base: Voltage gain but no current gain
Common emitter: Some voltage and some current gain, depending on the impedances in the emitter and collector circuits.
I've never used the common base configuration, I understand it is used mostly for the input stages of high frequency amplifiers.
Compared to other configurations, common emitter (CE) amplifiers tend to have higher input impedance and lower output impedance, and better-than-unity gain, which makes them very useful for both input buffering and voltage gain applications.
By contrast, common base (CB) amplifiers have low input impedance and higher output impedance. CB amps aren't so much for voltage gain as they are for power gain; with a CB configuration, any power sourced by the input is passed through to the load, in addition to the power added by the transistor itself, but this shows up as current gain.
