High-Speed Flip-Flops for the Millimicrosecond Region

The problem of designing high-speed flip-flops has been approached by dividing the circuit operation into steady-state and switching functions, the steady-state function being assigned to a slave flip-flop and the switching function to a driving circuit. Circuits, using conventional components and having a resolving time of 10m¿sec, are described. Resolving times as low as 2m¿sec have been attained by using a special beam-deflection tube as the slave flip-flop. These circuits dissipate considerably less power in the intervals between switching than conventional circuits.
