RADIATION RESISTANT BUFFER AMPLIFIER Russian patent published in 2010 - IPC H03F3/26 H03F3/50 H03F1/30 

FIELD: radio engineering.

SUBSTANCE: radiation resistant buffer amplifier comprises the first (1) and second (2) input transistors (T), bases of which are connected to input (3) of device, and emitters are connected to bases of the first (4) and second (5) output T and through the first (6) and second (7) current-stabilising dipoles are connected to the first (8) and second (9) buses of supply sources, besides emitters of the first (4) and second (5) outout T are joined to output (10) of device. The circuit includes the first (11) and second (12) additional T, emitters of which are connected to the first (8) and second (9) buses of supply sources via the first (13) and second (14) additional current-stabilising dipoles, bases are connected to emitters of the first (1) and second (2) input T, and collectors are connected to input (3) of device.

EFFECT: reduced input current and increased stability.
