Abstract
A transconductance filtering device with a flexible architecture that can selectively present a different topology and/or order beginning with the same initial structure is disclosed. For example, depending on the communications standard detected, the elementary cells of the filtering circuit required to form the adapted filter are selected and connected in such a manner as to obtain the configuration desired for the filtering means. As an example, the filter may be for use with a wireless communications system forming, in particular, a cellular mobile telephone. The filter is configurable by means of at least two elementary cells of the same structure and of controllable interconnection means each having an open or closed state.
