Basics of SoC I/O design: Part 1 – The building blocks

The integration of analog with digital and the increase number of on-chip features in mixed-signal controllers demand more complex I/O structures. Though they are sometimes some of the most neglected features of a chip, I/O (Input / Output pins) can represent a great deal of functionality in a SoC (System on Chip). The I/O structure in today’s SoC is …
