US 2024/0396537 A1 · MANAGING CAPACITOR VOLTAGE DEPENDENCE

Abstract

A system for reducing a voltage-dependent effect of a first capacitor caused by a first voltage may include the first capacitor, which may include a first physical spacing between a first capacitor terminal conductor of the first capacitor and a second capacitor terminal conductor of the first capacitor. The system may also include a second capacitor, which may include a second physical spacing between a first capacitor terminal conductor of the second capacitor and a second capacitor terminal conductor of the second capacitor, where the second physical spacing is different from the first physical spacing. The system may also include a compensation circuit, which may be arranged to receive and at least partially offset a voltage dependent signal contribution from each of the first and second capacitors for output to a signal-processing circuit.
