This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer. Controlled by the BCD value at the inputs, the output pin of the multiplexer ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.

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 ...

Industrial controls and variable-bias circuits sometimes require the services of voltage-to-resistance converters. But they can be difficult to implement. The simple approach shown in the figure ...
