FIELD: electronic equipment.
SUBSTANCE: invention relates to the field of analog microelectronics. Bipolar-field buffer amplifier contains input (1) and output (2) of the device, the first (3) voltage follower, the low-impedance output of which is connected to the output of device (2), the second (4) voltage follower, the low-impedance output of which is connected to the output of device (2), the first (5) and second (6) field transistors, the first (7) current-stabilizing two-terminal connected between the first (8) power supply bus and the source of the first ( 5) field transistor, reference current source (9), while collector circuit of the first (3) voltage follower is connected to the first (8) power supply bus, and the drain circuit of the second (4) voltage follower is connected to the second (10) power supply bus.
EFFECT: technical result consists in increasing the stability of the static mode and low noise level when the device is operating in the low temperature range with high linearity of the amplitude response.
