Device with two differential oscillators with pulsed power supply coupled to and in quadrature-phase with each other

Abstract

The present invention concerns 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 (L, C, C; L, C, C) respectively, which are apt to provide, respectively on first two and second two terminals (NODE, NODE; NODE, NODE), first two and second two oscillating signals (V, V; V, V), said first two oscillating signals (V, V) being in phase opposition to each other and in quadrature-phase with said second two oscillating signals (V, V), the device being characterised in that it comprises first generator electronic means (M-M) apt to detect first instants of passage through a first reference value of each one of said first oscillating signals (V, V) and to generate first power supply pulses for said second resonant electronic means (L, C, C) in second instants, and in that it comprises second generator electronic means (M-M) apt to detect third instants of passage through a second reference value of each one of said second oscillating signals (V, V) and to generate second power supply pulses for said first resonant electronic means (L, C, C) in fourth instants.
