FIELD: electronics.
SUBSTANCE: invention relates to circuitry, automation, industrial electronics and instrumentation. It can be used, in particular, in the form of buffer (decoupling) cascades and matching devices. Engineering problem is solved by that a non-inverting voltage repeater containing an operating amplifier is introduced with a set of four additional elements and the elements connection is changed, additional first and second resistors are interconnected in series, free terminal of the first of them is connected to the output of the existing operating amplifier, and free terminal of the second one is grounded, additional capacitor is connected parallel to the first additional resistor, common output of the first, the second additional resistors and the additional capacitor is connected to the non-inverting input of the additional operating amplifier, its output is connected to its inverting input, and also forms the output of the non-inverting voltage repeater relative to the grounding, common output of the inverting input and the output of the additional operating amplifier is connected to the non-inverting input of the existing operating amplifier.
EFFECT: technical result is higher accuracy of voltage transfer.
