From multivalued current mode CMOS circuits to efficient voltage mode CMOS arithmetic operators

We show that a 3-valued current mode CMOS 2-input BSC adder can be converted into a CMOS binary 4-2 counter or into a 1-digit Avizienis-like adder using a redundant number representation. Using a current mode algorithm to derive binary CMOS implementations of these arithmetic operators leads to equivalent or faster circuit implementation than the typical implementations that have been used until now
