A method for forming a conversion efficiency ratio of a circuit built with operation amplifiers and a device for implementation thereof (embodiments) relates to electronics, analogue nano-piko circuit engineering. The method for forming the conversion efficiency ratio of a circuit built with operation amplifiers consists in following: the said conversion efficiency ratio is set by feedback resistor rating. In two channels correlation of input resistors rating and value of amplification constant of the operational amplifier are set. According to the invention, for said correlation in every channel necessary scaling factor of input signal conversion is set, said signals are amplified, difference between signals is obtained and amplified to obtained a reference voltage, using the said voltage influence of in-phase component in input is compensated. The technical result is increase of accuracy of amplification while forming linear and scale amplification ratio and enhancement due to creation of an amplification system. |
