Switch-mode power supplies can use digital current-mode techniques for protection against peak currents, magnetic field "ratcheting," and input-voltage variations. Digital control of switch-mode power ...

Once in a while we come across the need to power some tiny analog circuitry, and off-the-shelf power supply ICs are just overkill for such tasks. This especially applies when your needs measure in ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...
