Abstract
Apparatuses, systems, and methods are disclosed for offset trimming for differential amplifiers. An apparatus includes a differential amplifier. A differential amplifier includes a non-inverting input, an inverting input, and an output coupled to the inverting input via a voltage divider. A first variable current source is coupled to a non-inverting input, so that increasing a current from the first variable current source increases a voltage at the non-inverting input. A second variable current source is coupled to an inverting input, and to an output via a voltage divider, so that increasing a current from the second variable current source decreases a voltage at the output.
