We present the basic structure and performance of CML current mode full adders, that are used as carry save adders (CSA) in combinatorial multipliers. A 1.2 /spl mu/m BiCMOS technology is used for simulations but the schematic assumes a 2.5-V power supply. Compared with binary voltage mode CSAs, the multivalued current mode CSAs have chip area and power dissipation advantage, but speed disadvantage. The current mode version is far more sensitive to power supply and temperature shifts. >
