Abstract
A sensor driver comprises a receiver and an interference mitigation element. The receiver is configured to acquire a resulting signal from a sensor electrode. The interference mitigation element is communicatively coupled with the receiver and is configured to receive interference data, generate an interference estimate from the interference data and a transfer function, and communicate the interference estimate to the receiver. The interference estimate removes charge from a resulting signal, mitigating effects of interference within the resulting signal.
