Abstract: 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 switching phase. The comparator is coupled to compare a voltage potential on the modulation capacitor to a reference and to generate a modulation signal in response. The charge dissipation circuit is coupled to the modulation capacitor to selectively discharge the modulation capacitor in response to the modulation signal.

A gate dielectric structure is disposed between the first gate conductor and the dielectric layer, and may include two or more dielectric films disposed in an alternating manner. The inter-gate dielectric structure may be disposed between the first gate conductor and the second gate conductor, and may include two or more dielectric films disposed in an alternating manner. The second gate conductor is formed in an L shape such that the second gate has a relatively low aspect ratio, which allows for a reduction in spacing between adjacent gates, while maintaining the required electrical isolation between the gates and contacts that may subsequently be formed.
