TWO-CYCLE BUFFER AMPLIFIER Russian patent published in 2010 - IPC H03F3/26 H03F3/45 

FIELD: radio engineering.

SUBSTANCE: invention may be used as buffer amplifier of analogue microchips of various functional purpose (for instance, repeaters of signals with high efficiency factor and increased loop amplification, drivers of communication lines, etc.). Two-cycle buffer amplifier (TBA) comprises input differential cascade (DC) with the first (2) and second (3) current leads. Output composite transistor (4), base (5) of which is connected to the first (2) current lead of DC (1), and emitter (6) is connected to outlet (7) of DBA. Differential circuit of potentials matching (DC) (8), having non-inverting (9) and inverting (10) inlets. Outlet inverting cascade of amplification (11), inlet of which (12) is connected to outlet (13) of DC (8), and outlet (14) is connected to outlet (7) of DBA, the first (15) current-stabilising dipole (CD) connected to the first (2) current lead of DC (1), the second CD (16). Non-inverting inlet (9) of DC (8) is connected to the second (3) current lead of DC (1), and the second CD (16), and inverting input (10) of DC is connected to outlet (7) of DBA.

EFFECT: improved coefficient of amplification by voltage and reduction of transmission error.
