A transconductor circuit, particularly according to the multi-tanh principle, having a first input node and a second input node, a first differential amplifier coupled to the first and second input nodes, and having a first offset voltage, and a second differential amplifier coupled to the first and second input nodes, and having a second offset voltage different from the first offset voltage. A first resistance circuit is coupled between the first differential amplifier and at least one current source, and a second resistance circuit is coupled between the second differential amplifier and the at least one current source. Varying of the current sources enables control of the transconductance without degrading linearity.
