Abstract
A multi-valued logic (MVL) circuit includes a MVL clock generator that generates a MVL clock signal having three or more ith MVL levels, a single MVL clock signal distribution network connected to the MVL clock generator, and three or more ith MVL selection circuits connected to the single MVL clock signal distribution network where i=0 to N and N>=3. Each ith MVL selection circuit corresponds to a specified ith MVL level. The ith MVL selection circuit outputs an ith binary clock signal having: (a) a first logic level whenever the MVL clock signal is equal to the ith MVL level and the ith data input receives the first logic level, (b) a second logic level whenever the MVL clock signal is equal to the ith MVL level and the ith data input receives the second logic level, and (c) a previous logic level of the ith binary clock signal whenever the MVL clock signal is not equal to the ith MVL level.
