HIGH-SPEED OPERATIONAL AMPLIFIER BASED ON "BENT" CASCODE Russian patent published in 2016 - IPC H03F3/00 

FIELD: radio engineering and communications.

SUBSTANCE: amplifier includes input field-effect transistors, current-stabilising bipole, output transistor, which are connected to input field-effect transistor, wherein first output transistor through current-stabilising bipole is connected to second power supply bus, second output transistor is connected to first input field transistor and through a third current-stabilising bipole is connected to a second power supply bus, a dynamic load circuit, matched with first power supply bus. Circuit includes additional field-effect transistors, additional bipolar transistors.

EFFECT: providing higher levels of output current of "bent cascode", higher efficiency of the operational amplifier in large signal mode, shorter time of establishing a transient process.
