A variety of logic-circuit techniques have been in use since the 1960s, when integrated logic first came into existence. In the beginning was Resistor-Transistor Logic (RTL). Then came ...

While working on recreating an “ancient” (read: 60-year-old) logic circuit type known as resistor-transistor logic, [Tim] stumbled across a circuit with an unexpected oscillation. The oscillation ...

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 ...
