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 ...

This CMOS two-input combination NAND/NOR gate is a three-input, fourpin logic gate. A p-channel enhancementtype MOSFET (Q1) and an n-channel enhancement-type MOSFET (Q4) form one complementary ...
