Abstract
A masterslice cell wireable to form any of a selected book set of two level differential cascode current switch basic circuits. Twenty percent increased performance is provided as compared with ECL masterslice circuits running at the same power. In spite of increased wire due to differential logic, and potential increased complexity in design software, the invention is actually readily adaptable to existing masterslice design systems.
