description An apparatus includes a first amplifier circuit (650a) and a second amplifier circuit (650b). The first amplifier circuit (650a) has a first output coupled to a first load circuit (670a) in a multi-output mode, and the second amplifier circuit (650b) has a second output coupled to a second load circuit (670b) in the multi-output mode. The apparatus further includes a first divert circuit (650d) and a second divert circuit (650c). The first divert circuit (650d) is configured to divert a first portion of a first amplified signal from the first amplifier circuit (650a) to the second load circuit (670b) in the multi-output mode. The second divert circuit (650c) is configured to divert a first portion of a second amplified signal from the second amplifier circuit (650b) to the first load circuit (670a) in the multi-output mode. L'invention concerne un appareil qui comprend un premier circuit amplificateur (650a) et un second circuit amplificateur (650b). Le premier circuit amplificateur (650a) comporte une première sortie couplée à un premier circuit de charge (670a) dans un mode multi-sortie et le second circuit amplificateur (650b) comporte une seconde sortie couplée à un second circuit de charge (670b) dans le mode multi-sortie. L'appareil comprend en outre un premier circuit de déviation (650d) et un second circuit de déviation (650c). Le premier circuit de déviation (650d) est configuré de sorte à dévier une première partie d'un premier signal amplifié provenant du premier circuit amplificateur (650a) vers le second circuit de charge (670b) dans le mode multi-sortie. Le second circuit de déviation (650c) est configuré de sorte à dévier une première partie d'un second signal amplifié provenant du second circuit amplificateur (650b) vers le premier circuit de charge (670a) dans le mode multi-sortie.
