FIELD: analog microelectronics.
SUBSTANCE: invention relates to the field of analog microelectronics. To achieve the effect, a source signal follower is proposed, which contains an input (1) and an output (2) of the device, an input field-effect transistor with a p-channel (3), an output n-p-n bipolar transistor (4), the first (5) power supply bus, a reference current source (6), the second (7) power supply bus. The drain of the input field-effect transistor with a p-channel (3) is connected to the first (5) power supply bus, the source is connected to the base of the output n-p-n bipolar transistor (4) and through a forward-biased p-n junction on the bipolar n-p-n-transistor (8) is connected to the output of the device (2), while the reference current source (6) contains the first (9) and second (10) auxiliary field-effect transistors with a p-channel, the gates of which are connected to the second (7) bus, the drains are connected to the output (2), and the sources combined and connected to the second (7) bus through two parallel-connected forward-biased p-n-junctions on the first (11) and second (12) auxiliary transistors.
EFFECT: creation of a signal repeater providing small values of the systematic component of the zero bias voltage.
