BUFFER AMPLIFIER Russian patent published in 2011 - IPC H03F3/26 H03F3/50 

FIELD: radio engineering.

SUBSTANCE: buffer amplifier includes the first (1) and the second (2) input transistors (T) the bases of which are connected to input (3) of the device; emitter of the first T (1) is connected to the base of the first output T (4) and collector of T (5) of the first controlled current source (CCS); emitter of the second input T (2) is connected to the base of the second output T (6) and collector of T (7) of the second CCS; at that, emitters of T (4) and T (6) are connected to output (8) of the device. To the scheme there introduced is the first T (9) and the second T (10), the bases of which are connected to output (8) of the device; collector of T (9) is connected to base of T (5) of the first CCS; emitter of T (9) is connected to collector of T (1) and to the first (11) additional current-stabilising bipole; collector of T (10) is connected to base of T (7) of the second CCS, and emitter of T (10) is connected to collector of T (2) and the second (12) additional current-stabilising bipole.

EFFECT: amplification of quickly changing analogue signals as to power, in structure of input cascades of analogue microchips of various functional purpose.
