AI-generatedIntermittent voltage recovery after discharge in X7R capacitors
Observed behavior In a sample-and-hold front end, an X7R ceramic capacitor is discharged to ground and then shows a residual voltage reappearing across its terminals seconds later. This matches the documented dielectric absorption (soakage) effect, where dipole relaxation in the dielectric causes partial voltage recovery after discharge. Constraints and unce
