Patent ID: 8253501

Claim:
A device having a first and a second differential oscillators coupled to and in quadrature-phase with each other, comprising first and second resonant electronic means respectively, which are configured to provide, respectively on first two and second two terminals, first two and second two oscillating signals, said first two oscillating signals being in phase opposition to each other and in quadrature-phase with said second two oscillating signals, wherein the device comprises first generator electronic means configured to detect first instants of passage through a first reference value of each one of said first oscillating signals and to generate first power supply pulses for said second resonant electronic means in second instants, and in that it comprises second generator electronic means configured to detect third instants of passage through a second reference value of each one of said second oscillating signals and to generate second power supply pulses for said first resonant electronic means in fourth instants, wherein said second instants are the instants at which the projection of a vector representative of a power supply pulsed signal comprising said first power supply pulses on the first Floquet eigenvector of state variables selected from the group comprising the state variables of said second resonant electronic means and the state variables of said second differential oscillator as a whole is not larger than a first value of maximum threshold and wherein said fourth instants are the instants at which the projection of a vector representative of a power supply pulsed signal comprising said second power supply pulses on the first Floquet eigenvector of state variables selected from the group comprising the state variables of said first resonant electronic means and the state variables of said first differential oscillator as a whole is not larger than a second value of maximum threshold.
