Récemment, nous avons proposé un filtre à condensateur commuté FIR à faible consommation d'énergie, construit avec des condensateurs ayant des capacités proportionnelles aux racines carrées des valeurs des coefficients de la fonction de transfert. Il est appelé filtre FIR de type cyclique semi-parallèle (SPCT). Dans cet article, nous présentons le filtre IIR SPCT. Il ne nécessite qu'un seul amplificateur opérationnel, ce qui lui confère une faible consommation d'énergie. Le filtre IIR SPCT a une capacité totale inférieure à celle d'un filtre de type cyclique parallèle (PCT) et une meilleure réponse haute fréquence que l'un des filtres à rapport de coefficient de fonction de transfert (TCR) IIR. Dans l'ensemble, le filtre IIR SPCT présente des performances moyennes par rapport aux filtres IIR PCT et TCR pour la capacité totale, le nombre de types d'impulsions d'horloge et la réponse haute fréquence.

Abstract: Recently, we proposed a low power consumption FIR switched-capacitor filter constructed with capacitors having capacitances in proportion to square roots of transfer function coefficient values. It is referred to as an FIR semi-parallel cyclic type (SPCT) filter. In this paper, we present IIR SPCT filter. It needs only a single operational amplifier, hence being low power consumption. The IIR SPCT filter has smaller total capacitance than one of the IIR parallel cyclic type (PCT) filter and better high frequency response than one of the IIR transfer function coefficient ratio (TCR) filter. As a whole, the IIR SPCT filter has middle performance of the IIR PCT and TCR filters for the total capacitance, the number of types of clock pulses, and high frequency response.
