Board-level designers often have concerns about the proper way to handle grounding for integrated circuits (ICs) which have separate analog and digital grounds. Should the two be completely separate ...

“Ground bounce” is the amount that a ground return rises or falls relative to the system's 0V reference, and, in a dc/dc-switching converter, ground bounce can be many volts, often because of changing ...

A buck-boost single-inductor dc-dc regulator provides bidirectional operation. In one direction the regulator takes current from the supercapacitor and produces a regulated voltage to the load. In the ...
