(EN) DISCRETE-TIME ANALOG, DIGITALLY PROGRAMMABLE FILTER AND METHOD
(FR) FILTRE ANALOGUE A TEMPS DISCRET NUMERIQUEMENT PROGRAMMABLE ET PROCEDE ASSOCIE
Abstract
(EN)
Aspects provide discrete-time analog, digitally programmable filtering. A filter includes a plurality of transistors coupled as a current mode circuit. Further included is a switch for use in switching the plurality of transistors in and out to tune the current mode circuit, wherein adjustable low bandwidth filtering using small silicon area without passive components is achieved.
(FR)
L'invention concerne, dans certains aspects, un filtrage analogue numériquement programmable. Un filtre comprend une pluralité de transistors couplés en circuit à mode courant. L'invention concerne également un commutateur utilisé dans l'activation et la désactivation de la pluralité de transistors pour accorder le circuit en mode courant, par filtrage à faible bande passante réglable au moyen d'une petite zone de silicium sans composants passifs.
