Abstract
Disclosed is a system that comprises an operational amplifier with adjustable operational parameters and a trimming module. The trimming module can adjust the operational parameters of the op-amp based on a memory value to compensate for an offset voltage of the op-amp. The trimming module can comprise successive approximation register (SAR) logic that controls the memory value. The SAR logic can be configured to detect a given memory value that causes an output voltage of the op-amp to be within a predetermined voltage interval when applying a predetermined common mode voltage to inverting and non-inverting inputs of the op-amp.
