Abstract
A variable-capacitance capacitor having first and second electrodes mobile with respect to each other and third and fourth electrodes insulated from the first and second electrodes, capable of receiving a control signal to vary the relative position of the first and second electrodes in order to vary the capacitance between the first and second electrodes, the capacitor further including a system for controlling the position of the second electrode with respect to the first electrode, the system being arranged so that, for at least one relative position of the second electrode with respect to the first electrode, the position of the second electrode with respect to the first electrode is independent from the voltage between the first and second electrodes.
