DIFFERENTIAL AMPLIFIER WITH HIGHER AMPLIFICATION RATIO BY VOLTAGE Russian patent published in 2012 - IPC H03F3/45

Abstract RU 2439783 C1

FIELD: radio engineering.

SUBSTANCE: device comprises an input differential cascade, the first and second output transistors, an equivalent load resistor, the first and second current-stabilising dipoles, the first and second resistors of a collector load.

EFFECT: higher amplification ratio by DA voltage as its collector load resistors are arranged as relatively low-resistance.
