Abstract
A processing system is disclosed. The processing system includes an amplifier configured to generate a feedback signal by amplifying each of multiple reduced noise signals based on a gain value and a cardinality of the reduced noise signals. The processing system also includes multiple charge integrators configured to obtain resulting signals from capacitive sensor electrodes coupled to a noise source and generate the reduced noise signals by mitigating noise in the resulting signals using the feedback signal.
