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 ...

Figure 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency. Figure 1 Just a couple of components are needed for a simple ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

Imec has used an optimised CMOS process to fabricate vertically stacked gate-all-around (GAA) silicon nanowire transistors in a functional ring oscillator. The demonstrator shows the enormous promise ...

Designers of VCO modules can reduce the size and increase the performance of these modules with a new device that combines in a single tiny package the company's NE894 transistor for oscillator ...
