FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering and communication. Technical result is achieved due to a high-speed differential operational amplifier, which comprises an input differential stage with the first and the second inputs, the first and the second phase-to-phase current outputs, the first reference current source, the first current mirror, the third current mirror matched to the second power supply bus, a correcting capacitor, a differential stage comprising the first and the second inputs, the first and the second phase-to-phase current outputs, an auxiliary input of an additional differential stage.
EFFECT: technical result is to increase the maximum rate of increasing the output voltage when operating the op-amp input transistors based on three current mirrors with microampere static currents.
