Abstract :
Complementary output switching logic (COSL) is used to define building blocks for ultra-high speed (~20 GHz) logic circuits. The family consists of the standard logic functions OR, NOR, AND, NAND and XOR. The building blocks include a new single gate inverter and various latch functions. Changes in the layout of the COSL gates are proposed to improve the uniformity of current distribution in the gates, which will, in turn, prevent unwanted field concentrations
