CASCODE DIFFERENTIAL AMPLIFIER Russian patent published in 2012 - IPC H03F3/45 

FIELD: radio engineering.

SUBSTANCE: cascade differential amplifier comprises an input differential cascade with the first and second current outputs, two output transistors, bases of which are connected with a source of shift voltage, two resistors, two sources of supply, two current mirrors, two correcting condensers and an additional resistor.

EFFECT: higher amplification ratio by voltage, elimination of an additional amplification cascade, reduction of general power consumption in comparison with multicascade amplifiers.
