Patent US9400298 - Capacitive field sensor with sigma-delta modulator - Google Patents
A capacitive sensor includes a switching capacitor circuit, a comparator, and a charge dissipation circuit. The switching capacitor circuit reciprocally couples a sensing capacitor in series with a modulation capacitor during a first switching phase and discharges the sensing capacitor during a second...http://www.google.ca/patents/US9400298?utm_source=gb-gplus-sharePatent US9400298 - Capacitive field sensor with sigma-delta modulator
