Figure 2 Schematic diagram of wire break detector using CMOS memory cell (shown in broken box). If using the CD40106, only one gate is needed for the oscillator (Schmitt inputs). An additional gate ...

Although several basic logic gates, including NOT, NAND, NOR, AND, OR 17,18,19,20, and the more complex five-stage ring oscillator have been fabricated 21, CNT-based logical circuits that are more ...

Fairchild’s proposed NOR logic circuit is upside down but identical to textbook NOR gates in CMOS. Operation is simple: The output Y can only be pulled low by the N devices if they’re all on ...
