Title (EN) DYNAMIC SIGNAL CONTAMINATION SUPPRESSION
(FR) SUPPRESSION DE CONTAMINATION DE SIGNAL DYNAMIQUE
Abstract:
(EN) A self-configurable amplifier and method of amplification, including an RF signal level detector having an input connected to an RF signal, and an output configured to produce a control signal responsive to a power level of the RF signal. The control signal is supplied to a parametric adjustment circuit that includes an input connected to the control signal, and an output configured to provide a negative feedback responsive to the control signal. The negative feedback is supplied to an RF amplifier that includes an input forming an input of the self-configurable amplifier, an output forming an output of the self-configurable amplifier, and a control port connected to the output of the parametric adjustment circuit, such that one or more parameters of the RF amplifier is responsive to the negative feedback.
(FR) L'invention porte sur un amplificateur auto-configurable et sur un procédé d'amplification, comprenant un détecteur de niveau de signal RF possédant une entrée connectée à un signal RF et une sortie configurée pour produire un signal de commande en réponse à un niveau de puissance du signal RF. Le signal de commande est fourni à un circuit d'ajustement paramétrique qui comprend une entrée connectée au signal de commande et une sortie configurée pour délivrer une rétroaction négative en réponse au signal de commande. La rétroaction négative est fournie à un amplificateur RF qui comprend une entrée formant une entrée de l'amplificateur auto-configurable, une sortie formant une sortie de l'amplificateur auto-configurable et un port de commande connecté à la sortie du circuit d'ajustement paramétrique, de sorte qu'un ou plusieurs paramètres de l'amplificateur RF sont sensibles à la rétroaction négative.
