DEVICE WITH TWO DIFFERENTIAL OSCILLATORS WITH PULSED POWER SUPPLY COUPLED TO AND IN QUADRATURE-PHASE WITH EACH OTHER

摘要

The present invention concerns a device having a first and a second differential oscillators (1, 2; 1' 2') coupled to and in quadrature- phase with each other, comprising first and second resonant electronic means (L1, C1, C2; L2, C3, C4) respectively, which are apt to provide, respectively on first two and second two terminals (NODE_1, NODE_2; NODE_3, NODE 4), first two and second two oscillating signals (VNODE_1, VNODE_2; VNODE_3, VNODE_4), said first two oscillating signals (VNODE_1, VNODE_2) being in phase opposition to each other and in quadrature-phase with said second two oscillating signals (VNODE_3, VNODE_4), the device being characterised in that it comprises first generator electronic means (M13- M24) apt to detect first instants of passage through a first reference value of each one of said first oscillating signals (VNODE_1, VNODE_2) and to generate first power supply pulses for said second resonant electronic means (L2, C3, C4) in second instants, and in that it comprises second generator electronic means (M 1 -M 12) apt to detect third instants of passage through a second reference value of each one of said second oscillating signals (VNODE_3, VNODE_4) and to generate second power supply pulses for said first resonant electronic means (L1, C1, C2) in fourth instants.
