Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

All modern digital logic consists of combinatorial logic and sequential logic. Combinatorial logic is made up of gates while sequential logic comprises of flipflops. Different transistors are ...

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 the ...
