Digital design with combinatorial gates like ... While this is simple, it also prevents you from building things like state machines, counters, and even CPUs. Circuits that use their own outputs ...

The resulting output (Figure 2) doubles an input frequency from 15MHz to 30MHz. A few simple selections configure this circuit for an application. The logic gate must operate from the desired supply ...

Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples ... Input-B to its gate terminal. The source terminal, labeled as Output-C, is the output of the ...
