METHOD OF CONTROLLING TRANSFER CONSTANT OF COMPUTING AMPLIFIER Russian patent published in 2016 - IPC H03F3/45 

FIELD: radio engineering, communication.

SUBSTANCE: method provides the control of the transfer constant of a computing amplifier by performing the scaled variation of the resistance of resistors of a four-terminal element of a negative feedback circuit; converting input voltage into charge current of a balancing capacitor, wherein the conversion slope is inversely proportional to the change in the transfer constant of the negative feedback four-terminal element; stabilising the phase shift of the feedback signal of the differential amplifier of the computing amplifier.

EFFECT: providing the highest and constant pass band of the computing amplifier in a wide range of variation of the transfer constant thereof when operating with both active and capacitive or active-capacitive load with considerable reactivity.
