A capacitor has first and second conducting plates and a dielectric region between the plates, wherein the dielectric region comprises two dielectric materials for each of which the variation of capacitance with voltage can be approximated by a polynomial having a linear coefficient and a quadratic coefficient, and wherein the quadratic coefficients of the two dielectric materials are of opposite sign. The capacitor comprises for example a first capacitor () and a second capacitor () that one connected in an anti-parallel manner. The insulating layer () of the first capacitor comprises silicon nitride and the insulating layer () of the second capacitor comprises silicon dioxide.
