WebDynamic offset cancellation techniques such as chopping, auto-zeroing, and correlated double sampling are often employed to suppress offset and flicker noise. However, these techniques could introduce some "side-effects" such as noise folding, increased input current, decreased input impedance, intermodulation distortion, etc., which should be ... WebNov 1, 2024 · An ultra-low power dynamic comparator is proposed with dynamic offset cancellation in this Letter. The dynamic offset voltage can achieve <0.5 LSB when common-mode voltage varies from 0.5V DD to V DD with the cascode current source for 10-bit SAR ADCs. The power consumption can be ultra-low since it has no power …
