| Abstract: | Some bassic issues regarding the estimation of power dissipation and techniques for logic synthesis of low power CMOS digital circuits are examined.The expression of the number of signal transitions as a function of the number of applied input vectors and input signal probabilities is derived.Some techniques used in the synthesis of combinational circuits,where the objective is to minimize the average power dissipation,are discussed.Finally,two theorems for low power logic synthesis are presented. |
