  • Phase and amplitude digital modulation circuit and method
    Patent number: 6831526
    Abstract: A method and a circuit for modulating a carrier signal (Se) with a signal (SCj) having at least a modulation cell (CMi) by phase shift for receiving two digital control signals (Scji, SCji2) representing at least part of the digital modulation signal (SCj). For at least a value of the digital modulation signal (SCj), the method consists in applying on at least a common modulation cell (CMi), two digital control signals (SCji1, SCji2) of identical value, the modulation cell (CMi) delivering a signal, called a modulated elementary signal (Ssi), which is null for the digital modulation signal value (SCj).
    Type: Grant
    Filed: January 9, 2003
    Date of Patent: December 14, 2004
    Assignee: Centre National d'Etudes Spatiales (C.N.E.S.)
    Inventors: Jerome Sadowy, Cyrille Boulanger, Jean-Claude Lalaurie, Luc Lapierre
  • Phase and amplitude digital modulation circuit and method
    Publication number: 20040021523
    Abstract: The invention concerns a method and a circuit for modulating a carrier signal (Se) with a signal (SCj) comprising at least a modulation cell (CMi) by phase shift for receiving two digital control signals (Scji, SCji2) representing at least part of the digital modulation signal (SCj). For at least a value of the digital modulation signal (SCj), the method consists in applying on at least a common modulation cell (CMi), two digital control signals (SCji1, SCji2) of identical value, said modulation cell (CMi) deliver a signal, called modulated elementary signal (Ssi), which is null for said digital modulation signal value (SCj).

  • Phase-shift keying electronic circuit with distributed structure
    Patent number: 6163230
    Abstract: The invention concerns a modulating electronic circuit with m phase status m.gtoreq.2 comprising a distribution line (6) with n similar dephasing cells (Ci) n.gtoreq.2, each comprising a transistor supplying on a derivative output (ODi) an out-of-phase signal (SDi); a secondary switching/modulating stage (4) controlled on the basis of a control signal; means for summing in phase the signals derived the switching/modulating stage (4).
