VLSI arithmetic with current mode multiple valued logic

A general design methodology for arithmetic operators in current mode multiple value logic is described. It is based on the interconnection of single output functions of one current, quantizers, through summing nodes and current replicator circuits. Some quantizers are known already: radix 4 sum and carry circuits. The authors present new circuits for the discrete pseudologarithm and antilogarithm, which together give a single digit multiply circuit. These form a complete set that allows any arithmetic circuit to be constructed
