  • Galvanic isolation coupling device
    Patent number: 10629382
    Abstract: A system including first and second electric or electronic circuits galvanically isolated from each other, and a coupling device coupling the first circuit to the second circuit, the coupling device including a variable-capacitance capacitor including first and second electrodes mobile with respect to each other, separated by an insulating region, and third and fourth electrodes electrically insulated from the first and second electrodes, capable of receiving a control signal to vary, by an electrostatic, electromagnetic, or piezoelectric actuation mechanism, the relative position of the first and second electrodes, to vary the capacitance between the first and second electrodes.

  • Capacitive logic cell
    Patent number: 10593485
    Abstract: A logic cell including a fixed assembly including a first electrode, a mobile assembly including a second electrode, and third, fourth, and fifth electrodes, wherein: the first, second, third, fourth, and fifth electrodes are insulated from one another; the first and second electrodes define a capacitor variable according to the position of the mobile assembly relative to the fixed assembly; the third electrode is connected to a node of application of a first logic input signal; the fourth electrode is connected to a node of application of a second logic input signal; the fifth electrode is connected to a reference node; and the position of the second electrode relative to the first electrode is a function of a combination of the first and second logic input signals.
