A Novel Current-Mode Quaternary Multiplier with Indian Vedic Architecture
Abstract: A multiplier is a fundamental block of any digital signal processing system. Urdhva Tiryakbhyam sutra, from ancient Indian Vedic mathematics, offers regular and hierarchical multiplier architecture. Alternatively, current-mode multi-valued logic results in reduced circuitry and effective utilization of interconnections. In this paper, a new 4×4 current-mode quaternary Vedic multiplier design is proposed. The multiplier has been simulated using 0.18 µm technology with a power supply of 1 V and a …
