The circuit comprises a first and a second pair of inputs (2, 2 min ; 3, 3 min ) and at least three pairs of outputs (20, 20 min ; 24, 24 min ; 21, 21 min ). The pairs of inputs serve to receive pairs of two input signals (V1, V1c, V5, V5c) which are substantially complementary to one another. At least two pairs of outputs (20, 20 min ; 24 , 24 min ) serve to supply pairs of two substantially complementary output signals. A first output (21) of the third pair of outputs (21, 21 min ) is coupled to a first input (2) of the first pair of inputs (2, 2 min ). The second output (21 min ) of the third pair of inputs is connected to a circuit node which is not one of the inputs of the first pair of inputs. This node is for example the first input (3 min ) of the second pair of inputs (Figure 9). Another possibility is to couple node to one end (38) of the impedance element (32) which has its other end coupled to the second input (2 min ) of the first pair of inputs. |
