  • Metal oxide semiconductor (MOS) capacitor with improved linearity
    Patent number: 9716188
    Abstract: A MOS capacitor with improved linearity is disclosed. In an exemplary embodiment, an apparatus includes a main branch comprising a first signal path having a first capacitor pair connected in series with reversed polarities and a second signal path having a second capacitor pair connected in series with reversed polarities, the first and second signal paths connected in parallel. The apparatus also includes an auxiliary branch comprising at least one signal path having at least one capacitor pair connected in series with reversed polarities and connected in parallel with the main branch. In an exemplary embodiment, the capacitors are MOS capacitors.
