"NEGATIVE IMPEDANCE AMPLIFIER", characterized by being essentially constituted by two transformers, each comprising a primary and a secondary, and an amplifying unit, the primary of one of which transformers is connected in series to the line while the secondary from the same transformer is connected to the input of the amplifier unit; at the same time that the primary of the second transformer is connected to the output of said amplifying unit and the secondary is connected in series with the line and with the primary number of the first transformer, with which the possibility of gain of the amplifying unit is it is used to reduce the dimensions of the transformers, the greater loss of the miniaturized transformers being compensated for by means of an increase in the gain of said amplifier unit.
