A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...

A relaxation oscillator is an oscillator based upon the performance of a physical system’s resending to equilibrium after being disturbed. It is a dynamical system within the oscillator continuously ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Designers seeking a quick and easy frequency source often use a relaxation oscillator (Fig. 1) based on digital gates such as the 74HC14 inverter with hysteresis. The oscillator is also useful in ...

CMOS relaxation oscillators have emerged as a pivotal technology in modern integrated circuits, offering a balance between low power consumption and simplicity of design. These oscillators utilise the ...
