The article contain the way of designing of invariant circuits of amplifying with application of amplifiers with multiplicative suppression of common-mode signals. There are a lot of offers of new principles of management by the amplifying factor of active schematics for biopotential amplifiers. Were developed a lot of invariant schematics of amplifiers which have more higher technical characteristics as dinstinct from classical schematics.
