Ripple Carry Adders (RCAs) made of approximate cells are used in many applications to reduce power dissipation and delay. Unlike its exact counterpart, an approximate RCA may have a non-commutative ...

Approximate cells can be used to design Ripple Carry Adders (RCAs) for realizing approximate addition in energy-efficient CMOS digital circuits. As inputs of approximate cells could be non-commutative ...
