Device for phase and/or amplitude modulation

A phase and/or amplitude modulation method, comprising at least, when the method performs a phase modulation:

• generation of a phase-modulated periodic signal of frequency FPRP;
• and
• application of the phase-modulated periodic signal of frequency FPRP to a control input of a TORP signal generator corresponding to oscillation trains periodically repeated at a frequency FPRP whose oscillations are of frequency FOL equal to N·FPRP, with N integer greater than or equal to 2, and each oscillation train of which has a duration of less than 1/FPRP, the TORP signal generator including at least:
• an oscillator capable of generating a periodic signal of frequency FOL, and
• a power supply circuit configured to be controlled by a periodic signal of frequency FPRP and connected to at least one power supply input of the oscillator such that it generates a power supply voltage of the oscillator which is non-zero only during part of each period 1/FPRP,
• or including at least, when the TORP signal generator is configured to perform an amplitude modulation with 2P different amplitude states, with P integer greater than or equal to 1:
• generation of a thermometric code signal coded on at least 2P bits and coding an amplitude modulation signal,
• application or not, depending on the value of each of the 2P bits of the thermometric code signal, of the periodic signal of frequency FPRP to each of the control inputs of 2P TORP signal generators, each TORP signal generator including at least:
• an oscillator capable of generating a periodic signal of frequency FOL, and
• a power supply circuit configured to be controlled by a periodic signal of frequency FPRP and connected to at least one power supply input of the oscillator such that it generates a power supply voltage of the oscillator which is non-zero only during part of each period 1/FPRP, and
• linear combination of the signals outputted by the 2P TORP signal generators,
• or including at least, when the TORP signal generator is configured to perform an amplitude and phase modulation with 2P different amplitude states, with P integer greater than or equal to 1:
• generation of a phase-modulated periodic signal of frequency FPRP;
• generation of a thermometric code signal coded on at least 2P bits and coding an amplitude modulation signal,
• application or not, depending on the value of each of the 2P bits of the thermometric code signal, of the phase-modulated periodic signal of frequency FPRP to each of the control inputs of 2P TORP signal generators, each TORP signal generator including at least:
• an oscillator capable of generating a periodic signal of frequency FOL, and
• a power supply circuit configured to be controlled by a periodic signal of frequency FPRP and connected to at least one power supply input of the oscillator such that it generates a power supply voltage of the oscillator which is non-zero only during part of each period 1/FPRP, and
