Patent 4985643 Issued on January 15, 1991. Estimated Expiration Date: April 24, 2010. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
A speed enhancement technique for CMOS circuits is disclosed. In the series of logic stages, nodes in the signal path of a pulse are set by preceding logic stages, then reset by feedback from subsequent logic stages. This eliminates the capacitive burden of resetting any given node from the input signal to allow substantially all of the input signal to be employed in setting the nodes to an active state rather than wasting part of the signal in turning off the reset path. The technique is illustrated as applied to RAM circuits.
