Abstract

VLSI-oriented arithmetic circuits based on the signed-digital (SD) number system are proposed. A new bidirectional current-mode circuit in MOS technology is effectively used for SD number arithmetic operations. The circuit interconnections can be drastically reduced in spite of the redundant SD number representation. A VLSI-oriented, very fast SD multiplier is designed that is based on parallel binary-tree addition scheme. The multiply time of an SD array multiplier based on 2- mu m design rules is less than 30 ns.
