CASCODE DIFFERENTIAL AMPLIFIER WITH INCREASED AMPLIFICATION RATIO Russian patent published in 2012 - IPC H03F3/45 H03F3/34

Abstract RU 2439787 C1

FIELD: radio engineering.

SUBSTANCE: cascode differential amplifier with increased amplification ratio comprises an input differential cascade, from the first to the fourth output transistors, a potentials' bias circuit, the first and second stabilising dipoles, the first and second collector load dipoles, an additional transistor.

EFFECT: higher limit values of amplification ratio by DA voltage in case of low-voltage supply.
