    hi

    i'm looking for i curcuit to act as a Analog buffer(some amplification is acceptible)

    my input signal is in the range of 0-300mV

    i tried a common-source amplifier... but i dont get a linear transfer characterists
    (i tried many different resistance values but no change)

    You want to use a "common emitter" type. The emitter resistor provides local
    feedback and consequent linearity.
