Abstract:
Differential output stage (200) of an amplification device, for driving a load, comprises a first (201) and a second (202) differential output stage portion. The first differential output stage portion (201) comprises: a first (M1PSW) and a second (M1NSW) output circuit; a first driving circuit (210) comprising a first biasing circuit (M2P, M3N, M4N, R11, I11); a second driving circuit (220) comprising a second biasing circuit (I41, R41, M4P, M3P, M2N). The first differential output stage portion (201) comprises: a third output circuit (M2PSW) connected between a first node (N1) of said first biasing circuit (M2P, M3N, M4N, R11, I11) and a first differential output terminal (01), having a third driving terminal (DT3) connected to a first driving terminal (DT1); a fourth output circuit (M2NSW) connected between a first node (N4) of the second biasing circuit (I41, R41, M4P, M3P, M2N) and the first differential output terminal (01), having a fourth driving terminal (DT4) connected to a second driving terminal (DT2).
