1. Adder of voltages comprising a summation point (16) whereto the first terminals of at least two resistors (15, 19, 24) of integrated type are connected, these resistors being integrated on a common substrate, characterized in that : - the second terminal of at least one of said integrated resistors (19) is connected to the first terminal of at least one resistor (21, 22) of discrete type, the second remaining terminals of the resistors of integrated type and of discrete type receiving the voltages to be added up, - the value of the resistor(s) of integrated type (19) whereto one (a plurality of) resistor(s) (21, 22) of discrete type is (are) connected, is large compared to the value of the resistor(s) of discrete type which is (are) associated thereto. |
