The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.
A common problem for digital potentiometers (DigiPots) is the effect of wiper resistance, which produces quite noticeable non-linearities of regulation at both ends of the resistance range. These ...
A new breed of electronically adjustable resistors promises to ease fine-tuning in sensors and other electronic devices. Adjustable resistors have come a long way from mechanical potentiometers set ...
