FIELD: information technologies. ^ SUBSTANCE: invention is related to data transfer from microcircuit chip to microcircuit chip, which uses method of current mode instead of generally accepted methods of differential transfer of voltage mode signals. Current pulse is introduced into one of two transfer wires based on signal value subject to transfer (for instance, logical "0" or "1") by driver in transmitting microcircuit chip. Current pulse is accepted as differential current signal in receiving unit in receiving microcircuit chip. Differential current signal is transformed by current comparators into differential signal of low span voltage. Differential voltage signal may be detected by receiver of operational amplifier, which produces according value of signal. ^ EFFECT: reduction of consumed power and electromagnet noise. ^ 8 cl, 6 dwg |
