LVPECL is an established high-frequency differential signaling standard that dates back to the 1970s and earlier when high-speed IC technology was limited to NPN transistors only. Since only an active ...

For high-speed clock and data systems, positive emitter-coupled-logic (PECL) – a differential signaling scheme – is emerging as a preferred alternative to single-ended CMOS and TTL logic. High-speed ...

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 ...

All existing transistors are based on the formation of junctions. Junctions are capable of both blocking current and allowing it to flow, depending on an applied bias. They are typically formed by ...
