  • Integrated capacitive device and integrated analog digital converter comprising such a device
    Patent number: 8649157
    Abstract: An integrated capacitive device includes an electrically conducting comb, at least some of whose teeth form first electrodes of capacitors, and electrically conducting fingers extending between the teeth of the comb so as to form second electrodes of the capacitors. The device includes a first finger-teeth set having a single reference finger forming a reference capacitor having a reference capacitive value, at least one second finger-teeth set including several fingers, the reference finger and the number of fingers of the second finger-teeth set or sets forming a geometric series with ratio two. At least one additional set includes a single additional finger forming, with at least one tooth of the comb, an additional capacitor having an additional capacitive value substantially equal to half the reference capacitive value.
