Can someone help me in the values of capacitors that should be place in this circuit in order to operate it properly as a voltage amplifier (small signal)
C4 and C6 have to be dimensioned related to an impedance, that's the sum of an output and an input impedance, not "both" impedances (however this may be achieved?). In the present case, the input impedance of next stage (in case of C4) as the higher value of both could be use for calculation.
C2 and C3 should be dimensioned in relation to 1/gm (≈ 26 mV/Ic) rather than R4 and R10. 1/gm beeing tenfold lower than the said resistors.
