Title (EN) LOW-POWER ASK DEMODULATOR
(FR) DÉMODULATEUR ASK DE FAIBLE PUISSANCE
(KO) 저전력 ASK 복조기
Abstract: front page image
(EN)The present invention relates to a low-power, highly integrated ASK demodulator. The ASK demodulator according to one embodiment of the present invention comprises: a half wave rectifier for half-wave rectifying a received signal; an envelope sensor for detecting from the half-wave rectified signal an envelope having at least a preset size; a signal stabilizer for allowing the enveloped detected signal to be output stably regardless of the elapsed time; and a buffer for correcting the enveloped detected signal to get closer to a digital signal. The ASK demodulator of the present invention consumes less power than conventional FSK or PSK demodulators, and has a higher integration level than demodulators that typically include a resistor element or a capacitor, thereby making it suitable for communication equipment in a mobile environment.
(FR)La présente invention porte sur un démodulateur ASK fortement intégré de faible puissance. Le démodulateur ASK selon un mode de réalisation de la présente invention comprend : un redresseur simple alternance pour réaliser le redressement simple alternance d'un signal reçu ; un détecteur d'enveloppe pour détecter, à partir du signal redressé simple alternance, une enveloppe ayant au moins une taille prédéfinie ; un stabilisateur de signal pour permettre au signal à enveloppe détectée d'être délivré de façon stable indépendamment du temps écoulé ; et un tampon pour corriger le signal à enveloppe détectée pour le rapprocher d'un signal numérique. Le démodulateur ASK de la présente invention consomme moins d'énergie que des démodulateurs FSK ou PSK classiques, et présente un plus haut niveau d'intégration que des démodulateurs qui comprennent typiquement un élément résistif ou un condensateur, ce qui le rend approprié pour un équipement de communication dans un environnement mobile.
(KO)본 발명은 저전력 고집적의 ASK 복조기에 관한 것이다. 본 발명의 일 실시예에 의한 ASK 복조기는 수신 신호를 반파 정류하는 반파정류기와, 반파 정류된 신호로부터 소정 크기 이상의 포락선을 검출하는 포락선 감지부, 상기 포락선 검출 신호가 시간의 경과에 상관없이 안정적으로 출력되도록 하는 신호안정기, 및 상기 포락선 검출 신호가 디지털 신호에 가까워지도록 보정하는 버퍼부를 포함한다. 본 발명의 ASK 복조기는 종래의 FSK나 PSK 복조기에 비해 적은 전력을 소비하고 통상의 저항 소자나 커패시터로 구성되는 복조기에 비해 집적도를 높일 수 있으므로 모바일 환경의 통신 기기에 적합하다.
