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 ...

Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...
