Current Mode Circuits for Multiple-valued Logic and Residue Number System Arithmetic
نویسندگان
چکیده
This paper presents new structures of circuits: adders and D triggers based on the current mode gates – digital elements operating with constant, continuous power supply current. Current mode circuits do not perturb the analogue part of the chip integrated on the same die through the parasitic coupling across the substrate with the same strength as voltage mode circuits do. Designed circuits are destined for multiple-valued logic (N-radix) or residue number system (RNS) arithmetic (modulo N). Proposed structures are scalable and their dynamic parameters do not depend on value of N. All proposed structures were successfully tested using both SPICE simulator and special prepared MPUK program (logical level simulations).

Complexity of silicon integrated circuits (IC) in very large scale of integration (VLSI) using binary logic is reaching a point where most of the silicon area is occupied with interconnecting lines among devices on the chip, which represents a drawback of the approach. First implication of the high wiring complexity is increased packing complexity with increased number of pins (in today's VLSI ...
