Patent number: 8115556Abstract: The device resonant comprises a plurality of synchronized oscillators. Each oscillator comprises a resonator which comprises detection means providing detection signals representative of oscillation of the resonator to a feedback loop connected to an excitation input of the resonator. The detection signals control the conductivity of the feedback loop of the oscillator. The excitation inputs of all the resonators are connected to a common point which constitutes the output of the resonant device. A capacitive load is connected between said common point and a reference voltage.Type: GrantFiled: February 23, 2010Date of Patent: February 14, 2012Assignee: Commissariat a l'Energie AtomiqueInventors: Laurent Duraffourg, Philippe Andreucci, Eric Colinet, Sebastien Hentz, Eric Ollier
