REPRESENTATION OF A GAIN CONSTANT OF ACTIVE CIRCUIT OF OPERATIONAL AMPLIFIER AND ALL-PURPOSE AMPLIFIER FOR ITS EMBODIMENT (VARIANT)

摘要

Representation of a gain constant of active circuit of operational amplifier and all-purpose amplifier for its embodiment (variants) relates to electronics of analog circuit technique and may be used in broad range of amplifiers for different purpose, for example for amplification of boundary potentials. In accordance with the method, resistance of input resistors of direct transmission of inverting and noninverting inputs is established equal to proper gain constant of the operational amplifier, nominal value of feedback resistors is assigned value of gain constant of active circuit made on operational amplifier. The technical result is enhancement accuracy of amplification.
