Amplifier a multiple entrees and multiple outputs of the pseudo - entrees

摘要

The present invention relates to an amplifier capable of providing a plurality of output signals, these output signals being controlled by a plurality of input signals. An amplifier with multiple inputs and multiple outputs according to the invention comprises an input terminal common (10), 4 terminals of the input signal (11) (12) (13) (14), 4 terminals of the output signal (21) (22) (23) (24), an amplifier with a common terminal (9), 4 under - active circuits (30) and a feedback network (40). Each under - active circuit (30) has an input terminal under - circuit connected to one of the terminals of the input signal (11) (12) (13) (14), an output terminal under - circuit connected to one of the terminals of the output signal (21) (22) (23) (24), and a common terminal under - circuit. The feedback network (40) is 4 terminals "c" and a terminal "r". Each of said terminals "c" of the feedback network (40) is coupled to the common terminal under - circuit of one of said under - active circuits (30). The output terminal of the amplifier of the common terminal (9) is coupled to said terminal "r" of the feedback network (40).
