This Ideas for Design issue features three power-related ideas—each representing a different aspect of the technology.

The first discusses how to make a charge pump that delivers a regulated 2.5 V with low quiescent current, making it a good fit for MCUs. In the second entry, a hex inverter is used to create an oscillator and Class-D amp that drives MOSFETs to build a virtual ground. The third Idea for Design how exponential diode model analysis can be applied to size an LED array’s drive current.
