Power Systems-On-Chip

The book gathers the major issues involved in the practical design of Power Management solutions in wireless products as Internet-of-things. Presentation is not about state-of-the-art but about appropriation of validated recent technologies by practicing engineers. The book delivers insights on major trade-offs and a presentation of examples as a cookbook. The content is segmented in chapters to make access easier for the lay-person.
