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 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...
Modern circuit design is a “mixed signal” endeavor thanks to the availability of sophisticated process technologies that make available bipolar and CMOS (Complementary Metal Oxide Semiconductor), ...
