I am trying trying to make such a circuit which amplify AC signal comming from sensor(Sensor may be any one, no talk on sensor). Sensors output is varing from 0~20mVolts feeding this output to OPAMP (TL072) amplify this output, now ouput is 0~1.25 Volts coming from opAMP output, Now the problem is how to super impose this wave to a DC level of 1.25 Volts using OPAMP.
I mean i want to amplify the AC signal and want to change the DC level to 1.25 Volts using opAMP.
In simple First picture is Input & Second picture is output.
How we do this using opAMP, guide me.
Thanks.
