Abstract
The invention relates to an integrated circuit arrangement with an active filter comprising transconductance stages, each being adjustable by means of a bias current to be supplied, and comprising a tuning device for tuning the filter, which tuning device adjusts the bias currents of the transconductance stages, wherein the tuning device adjusts the bias current of a first transconductance stage, for the purpose of achieving a desired characteristic of this transconductance stage, and adjusts the bias current of at least one further transconductance stage such that the transconductance of this further transconductance stage deviates from the transconductance of the first transconductance stage by a certain value.
