Abstract:
An amplifier circuit can have a differential input. A common-mode signal present at the differential input can induce an offset voltage at an output of the amplifier circuit. A compensation can be performed to reduce or eliminate such an offset, such as at a first temperature. Circuits and techniques for drift correction can be performed, such as to correct for residual offset error across an entirety of a specified operation temperature range. In an example, first and second drift correction signal generator circuits can be used, such as to provide signals proportional to a common mode voltage, but having different temperature coefficients.

Claim (Index 9):
The electronic circuit of  claim 8 , comprising a scaling circuit configured to scale the first and second drift correction signals in proportion to the common mode input signal, the scaling circuit including an adjustable impedance to reduce or suppress a second output offset voltage corresponding to a second temperature, different from the first temperature.
