A new dynamic CMOS technique which is fully racefree, yet has high logic flexibility, and logic inversion is provided, which means higher logic flexibility and less transistors for the same function.
Abstract
Describes a new dynamic CMOS technique which is fully racefree, yet has high logic flexibility. The circuits operate racefree from two clocks /spl phi/ and /spl phi/~ regardless of their overlap time. In contrast to the critical clock skew specification in the conventional CMOS pipelined circuits, the proposed technique imposes no restriction to the amount of clock skew. The main building blocks of the NORA technique are dynamic CMOS and C/SUP 2/MOS logic functions. Static CMOS functions can also be employed. Logic composition rules to mix dynamic CMOS, C/SUP 2/MOS, and conventional CMOS will be presented. Different from Domino technique, logic inversion is also provided. This means higher logic flexibility and less transistors for the same function. The effects of charge redistribution, noise margin, and leakage in the dynamic CMOS blocks are also analyzed. Experimental results show the feasibility of the principles discussed.
