Abstract: A continuous-time filter comprising at least one amplifier and at least one passive element. The amplifier comprises at least one input terminal and at least one output terminal and the passive element is positioned between the terminals. In addition the amplifier is provided with a transconductance gain. The filter comprises circuit means suitable for correlating the transconductance gain of the amplifier with the passive element.
