OUTPUT CASCADE OF RAPID ACTION OPERATIONAL AMPLIFIER Russian patent published in 2007 - IPC H03F3/00 G05F3/26 

FIELD: radio engineering and communications.

SUBSTANCE: device contains first output transistor (1), collector of which is connected to load (2) of output cascade, emitter - through first auxiliary resistor (3) is connected to first power bus (4), and the base is connected to first source of support current (5) and through first directly shifted p-n transition of transistor (6) is connected to first input (7) of output cascade, where between first input of output cascade and first bus of power supply (4) the second auxiliary resistor (8) is coupled, the circuit also includes first additional transistor (9), base of which is connected to first input (7) of output cascade, the collector is connected to load (2) of output cascade, and emitter is connected to first bus of power source (4).

EFFECT: increased operation speed of output cascade.
