    Abstract: The invention relates to a transconductor circuit with a differential input and a single output, comprising two input transistors (M1, M2) whose primary conduction terminals (D1, S1, D2, S2) are respectively connected together; in this way, variations in load current and voltage can be made lower, thereby also lowering distortion from changes in their transconductance.

    Abstract: The transconductor system in accordance with the present invention is the type comprising a first transconductor circuit (C1) having differential mode transconductance equal to a first value and common mode transconductance equal to a second value and is characterised in that it comprises a second transconductor circuit (C2) connected in parallel with said transconductor circuit (C1) having common mode transconductance substantially equal in modulus to said second value and of opposite sign.
    In this manner the common mode current signal at the output is greatly reduced.
