Dual-input current-mode gate using for digital signal processing in mechatronic systems

摘要

The aim of this work is to propose an application of new multi-input, current-mode gates, especially new, accomplishing the logical function NOR to implement the T-type standard logical function, and a dual input gate. Current-mode gates consume almost current primarly 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. The 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 the T-type standard logical function for which for hardware implementation, a new dual-input current-mode gate is suggested, which in effect reduces the hardware complexity of the projected CMCL (Current-Mode Current Logic) system.
