Here is a Web site by a guy who designed working versions of all the basic logic gates, that is the NOT, OR, NOR, AND, and NAND gates, with Lego blocks.

X-REL Semiconductor introduces its High-Temperature multi-function logic gates: XTR54000. X-REL Semiconductor introduces its High-Temperature multi-function logic gates: XTR54000. Intended for ...

You can assemble a pulse-generation circuit from a simple Schmitt-input AND gate plus a resistor-capacitor timing network. However, if you need a logic function that's not a standard catalog item, you ...

You can use the circuit described in this DesignIdea to estimate voltages across 10- to 100-MΩresistances. It also works for reverse-biased diodes. The common CMOS gates in Figure 1 have aninput ...

A technical paper titled “Analysis of Logic-in-Memory Full Adder Circuit With Floating Gate Field Effect Transistor (FGFET)” was published by researchers at Konkuk University, Korea National ...

We’ve always been fascinated at the number of ways logic gates can spring into being. Sure, we think of logic gates carrying electrons, but there are so many other mechanical means to do the same ...
