Abstract
Sample-and-hold (S/H) circuitry operating in track and hold phases and having a first S/H circuit with a first hold capacitor at which a first voltage value is maintained in the hold phase, and a dielectric absorption (DA)-suppressing circuit connectable to the first hold capacitor for operating the S/H circuitry in an additional phase after completing the hold phase and before entering the track phase. The DA-suppressing circuit is configured to supply the first hold capacitor, during an operation in the additional phase, with a second voltage value that is negatively correlated with the first voltage value.
