Differential amplifier with two signal branches (Q1/2, 3/4, 7/8) each connected in series with a common current source (Q14) of a power supply source (+V, -V) and each having a signal input (+, -). It includes between each of these signal inputs and the common current source a parallel signal branch (Q5/6, 9/10, 11, 12) having a low impedance as compared to that of said current source and being able to establish a substantially constant voltage between each of said inputs and the junction point (A) of said branches and said current source (Q14). |
