sine wave oscillator

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

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

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.
