Self-timed CMOS static logic circuit

摘要

A Self-Timed CMOS Static Circuit Technique has been invented that provides full handshaking to the source circuits; prevention of input data loss by virtue off interlocking both internal and incoming signals; full handshaking between the circuit and sink self-timed circuitry; prevention of lost access operation information by virtue of an internal lock-out for the output data information; and plug-in compatibility for some classes of dynamic self-timed systems. The net result of the overall system is that static CMOS circuits can now be used to generate a self-timed system. This is in contrast to existing self-timed systems that rely on dynamic circuits. Thus, the qualities of the static circuitry can be preserved and utilized to their fullest advantage.
