PN junction (Doping)

GlobalFoundries launches industry's first 22nm FD-SOIL technology platform at a 20 percent smaller die size and 10 percent fewer masks than 28nm, as well as nearly 50 percent fewer immersion lithography layers than foundry FinFET.

This article discusses charge-pump DC/DC converters and introduces a design for an inductorless bipolar power-supply circuit.

You can’t beat the efficiency of switch-mode power supplies, and you can avoid the design-complexity issue by using DC/DC modules such as those in the OKDx-T/90 series.
