Dynamic logic circuits operating in a differential mode for array processing

摘要

The disclosure teaches various logic circuits operating with Dynamic Differential Logic (DDL). In a particular embodiment MOS transistors of n-channel type are used with circuits arranged to avoid any dc path from clock input to ground. The input capacitance of the active devices is used for temporary storage thereby reducing circuit complexities. Coupling between stages is provided by clock driven transistors connected so that the transistor at the higher voltage side cuts off early in the period of clock pulse decay, thereby isolating adjacent stages without unnecessary delay. The use of such circuits in array processors is described.
