The urge to replicate the venerable 555 in nothing but vacuum tubes is understandable, as it uses little more than a pair of comparators and a flip-flop, circuits [David] has already built vacuum ...

Figure 4 and 5 represent the transistor level schematic that show how a typical asynchronous RESET type flip-flop can be converted into the proposed circuit which can function as either RESET or SET ...

A two bit flip-flop can be designed to have a single cell row height or ... This also means that the short-circuit current requirement of multibit flops would be higher than a single bit flop in a ...

Static RAM is fast because the six-transistor configuration of its pretzel-like flip-flop circuits keeps current flowing in one direction or the other (0 or 1). The 0 or 1 state can be written and ...
