Figure 1 The XOR logic element and its analog using discrete elements.. The second variant of the 2XOR element is shown in Figure 2.Transistors Q1 and Q2, as well as resistor R2, serve as the 2AND ...

Resistor logic; diode logic; direct coupled transistor logic; resistor-transistor logic (RTL); diode-transistor logic (ETL); transistor-transistor logic (TTL); emitter coupled logic (ECL). The ...

DTL stands for diode-transistor logic and it was popular in “930-series” logic devices. I used wire-wrap or point-to-point solder-connection breadboards. But they became a pain when I needed to modify ...

Consequently, nobody has been able to make reliable diodes, transistors or logic gates out of silicon nanowires. Today, Massimo Mongillo et amis at the Universite Joseph Fourier, Grenoble, in ...
