Dans le domaine de l'ingénierie biomédicale, non seulement des filtres passe-bas pour l'élimination des hautes fréquences, mais également des filtres coupe-bande pour supprimer les interférences des lignes électriques sont nécessaires pour traiter les biosignaux basse fréquence. Pour l’intégration de filtres basse fréquence, la mise en œuvre de puces de grandes capacités constitue une difficulté majeure. En tant que méthodes permettant d'améliorer les capacités avec une petite surface de puce, l'utilisation de multiplicateurs de capacité est efficace. Cette lettre décrit la conception d'un filtre coupe-bas basse fréquence intégré utilisant des multiplicateurs de capacité. Deux points principaux sont présentés. Premièrement, un nouveau multiplicateur de capacité flottant est proposé. Deuxièmement, une technique permettant de réduire le nombre de multiplicateurs de capacité est proposée. Grâce à cette technique, la consommation d'énergie est réduite. Les techniques proposées sont appliquées à un filtre coupe-bas passe-bas du 3ème ordre. Les résultats de simulation montrent l'efficacité des techniques proposées.

Abstract: In a field of biomedical engineering, not only low-pass filters for high frequency elimination but also notch filters for suppressing powerline interference are necessary to process low-frequency biosignals. For integration of low-frequency filters, chip implementation of large capacitances is major difficulty. As methods to enhance capacitances with small chip area, use of capacitance multipliers is effective. This letter describes design consideration of integrated low-frequency low-pass notch filter employing capacitance multipliers. Two main points are presented. Firstly, a new floating capacitance multiplier is proposed. Secondly, a technique to reduce the number of capacitance multipliers is proposed. By this technique, power consumption is reduced. The proposed techniques are applied a 3rd order low-pass notch filter. Simulation results show the effectiveness of the proposed techniques.
