SELECTIVE AMPLIFIER Russian patent published in 2013 - IPC H03F3/45 

FIELD: radio engineering, communication.

SUBSTANCE: in the amplifier an emitter of the first (1) output transistor is connected with a current input of a device (5), between a collector of the second (2) output transistor and the first (8) bus of a supply source there are AC-connected serially joined the first (10) and second (11) correcting capacitors, the common unit of which via a frequency-setting resistor (12) is connected with the input of an additional current mirror (13), besides, the inverting output of the additional current mirror (13) is connected with the first (8) bus of the supply source, and a common non-inverting output (14) of the additional current mirror (13) is connected with the current input of the device (5).

EFFECT: reduced total power consumption of a selective amplifier.
