Common base Amplifier

Hi
here is one more topic related to BJT Configuration. There are three types of configurations
1. Common Base
2. Common Collector
3. Common Emitter
Common Base:
In this type of configuration base terminal of BJT is common between input loop and output loop. Input loop of BJT CB is emitter to base and output loop is collector to base.

when input applied across RE then there are two case 

1. when Vin > 0 then BJT Conduction reduce toward off and then max Ic flow through output.

2. & when Vin < 0 then BJT Conduction increase toward saturation low Ic flow through output and Vout reduce.

and we can find the Vout = Vcb = Vcc - IcRc
