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

oops- this should work better:

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.

Oh yeah?- Who says that's the "proper way", Miss Priss?
