The aim of this work is to proposed an application of new multi-input, current-mode gates, especially new, accomplishing logical function NOR to implement T-type standard logical function, dual input gate. Current-mode gates consume almost current from the power supply and therefore are suitable for mixed mode operations. Contrary to voltage mode digital gates, presented in the paper current mode gates do not produce strong voltage and current fluctuations in the common substrate of the mechatronics system. Current-mode gates algebra differs from Boole’s one, as besides logical states “0” and “1” also state “-1” occurs. Thanks to “-1” state it is easy to implement T-type standard logical function for which for hardware implementation, new dual-input current-mode gate is suggested, which in effect reduces hardware complexity of projected CMCL (Current–Mode Current Logic) system.
