Title (EN) LOW NOISE FRONT-END FOR A HEART RATE MONITOR USING PHOTO-PLETHYSMOGRAPHY
(FR) APPLICATION FRONTALE À FAIBLE BRUIT POUR MONITEUR DE FRÉQUENCE CARDIAQUE UTILISANT LA PHOTOPLÉTHYSMOGRAPHIE
Abstract:
(EN) An apparatus is provided for monitoring heart rate. The apparatus comprises various components to effectively reduce photodiode capacitance. The apparatus includes: an amplifier; a first current source; a first pair of resistors coupled to the first current source and the amplifier; a pair of devices coupled to the first pair of resistors; a photo-diode coupled to the pair of devices; a second pair of resistors coupled to the pair of devices and the photo- diode; and a second current source coupled to the second pair of resistors.
(FR) L'invention concerne un appareil pour la surveillance d'une fréquence cardiaque. L'appareil comprend divers composants pour réduire efficacement la capacité d'une photodiode. L'appareil comprend : un amplificateur ; une première source de courant ; une première paire de résistances couplées à la première source de courant et à l'amplificateur ; une paire de dispositifs couplés à la première paire de résistances ; une photodiode couplée à la paire de dispositifs ; une seconde paire de résistances couplées à la paire de dispositifs et à la photodiode ; et une seconde source de courant couplée à la seconde paire de résistances.
