The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is … ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computatio… ...

Use #2: Diode Logic Gates. You can build simple logic gates using diodes. You can create an n-input OR gate or AND gate using 1 diode per input (Fig. 8). 8.

Figure 1 illustrates how YES, NOT, AND, OR, NAND, and NOR gates are implemented in RFL using a 2N7000 N-channel MOSFET and a 5V supply. (Note that the XOR and XNOR functions have been omitted here, ...

Figure 5: Transformers turn logic gates into live drivers. V CC /2 at the center tap lets the voltage induced on the logic high side (due to the pulldown on the logic low side) from becoming diode ...

Using DNA and harmless gut bacteria, scientists at Imperial College London have built biological logic gates that could lead to the development of a new generation of microscopic biological ...

They are the most advanced biological logic gates ever created, claims the university. “We have demonstrated that we can replicate these parts using bacteria and DNA, we hope that our work could lead ...

Pairs of gates can be used to create AND and OR logic based on the levels of output observed. When a pair of gates are both off, output is low; it's higher for a one-on/one-off situation (OR) and ...
