Hi, i've found the circuit shown in figure below
![ib6fin.jpg ib6fin.jpg](https://www.edaboard.com/data/attachments/36/36936-abf9a3310859c403b0345b19dd582e35.jpg)
the circuit connected to the positive pin of operational amplifier seems to be useful to regulate the offset of OP AMP by trimming the value of resistors R1 and R2.
I don't understand how this circuit works and how it is able to regulate the offset, could you help me please?
