    here it's my sine wave osc.

    The signal output is from -14mV to 14mV...

    How could i get an adjustable offset from 0 to 28 mV output , with
    simple circuitry ?

    thanks

    You mean you want to add a DC to your signal? Since you have Cout you'll
    have to do it after this capacitor. A proper way to do this is to add a
    summing opamp with two inputs, one for your sine and one for the DC offset.
    Maybe there is one left in your LM324. Do not add a cap to the output of the
    summing opamp.
