AC analysis:

All the parameter of this configuration is same as common emitter with RE. A Only change is that put the value of RE =  0.

Voltage gain:

           Av = Vo/Vin

                             = -g_m(Rc||R_L||r_o)

Current gain:

                      Av = -g_mr_𝝿  = -𝜷

Input resistance: 

                           R_iB =  r_𝝿

                                                    Ri =R_TH||Ri_B

Ri_B  is input resistance looking into base of BJT

Ri is input resistance  of amplifier 

Ris is input resistance looking from source 

Output resistance:  Ro = Rc||Ri_B
