METHOD FOR RAISING SPEED OF OPERATIONAL AMPLIFIERS HAVING DIRECTLY COUPLED STAGES Russian patent published in 2006 - IPC H03F3/45 

FIELD: radio and communications engineering.

SUBSTANCE: proposed method designed for application in broadband and pulse signal amplifiers of miscellaneous analog interface structures to enhance their speed by 5 to 10 times using micron technology with layout standards equal to or higher than 1.5 - 2 μm includes generation of additional charge-discharge current for correcting capacitor 3 (Fig. 1) proportional to difference 8 between current value of voltage across correcting capacitor and instant output voltage of auxiliary differential stage 6 identical to limited-output-current nonlinear input differential stage 1 connected to its inputs.

EFFECT: enhanced speed.
