An operational amplifier includes a pre-amplifier circuit, a first trim circuit, and a second trim circuit. The pre-amplifier circuit is to include a differential pair and receive an input voltage. The first trim circuit is to produce an offset voltage correction current and provide the offset voltage correction current to the pre-amplifier circuit to correct an offset of the operational amplifier. The second trim circuit is to produce a common mode voltage (VCM) correction current, provide the VCM voltage correction current to the pre-amplifier circuit, and cause the VCM correction current to have a non-zero value to reduce a correction caused by the offset voltage correction current when the input voltage is within a mid voltage input range. The pre-amplifier circuit is to apply the offset correction current and the VCM correction current to output signals of the differential pair.
