Abstract:
Apparatuses and methods for providing offset compensation include a primary amplifier which includes a first output, a second output, a first load input, and a second load input, a first feedback loop connected to the primary amplifier and which includes a first switch located between the first output of the primary amplifier and the first load input, and a first sampling capacitor coupled to the first switch between the first switch and the first load input and a second feedback loop connected to the primary amplifier and which includes a second switch located between the second output of the primary amplifier and the second load input, and a second sampling capacitor coupled to the second switch between the second switch and the second load input.
