This full adder is constructed using two Feynman gates and a multiplexer. Fig. 8: Internal RTL of a reversible full adder. A Feynman Gate is a 2*2 reversible logic circuit. This gate placed in the ...

While it is true that you can build logic gates using switch logic (that is, ... And even if they don’t use relays to do it, some FPGAs use mux-based logic inside.

This paper designs an 8:1 multiplexer with CMOS Transmission Gate Logic (TGL) using the power gating technique, which reduces the leakage power and leakage current in active mode.

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (W… ...
