Structure of Wave Cascade The definitions presented in this section are based on and, with some modifications. Definition. A complex Maitra term is recursively defined as follows: (1)Constant 0 (1) Boolean function is a Maitra term. (2)A literal is a Maitra term. (3)If M i is a Maitra term, a is a literal, and G is an arbitrary two-input Boolean function, then M i+1 = G( a, M i+1 ) is a Maitra term. –Additionally, it is required that each variable appears in each Maitra term only once and that the same variable ordering is used to represent all Maitra terms. Previous authors restricted the two-input functions used in the Maitra terms to only functions AND, OR, and EXOR. For the purposes of reversible logic synthesis, on the other hand, it is better to use the above more general definition. In a variation of our algorithm targeting low-power CMOS implementation, G cannot be an EXOR function and its complement, NEXOR.
