Happy Wednesday, everyone.
Today's top story dives into the different ways that noise can impact high-speed analog signal chains. But understanding the problem is only first step to solving it. The article also covers how to apply basic noise principles to each analog-to-digital converter (ADC) input node to minimize noise.
I also recently covered NXP's new 18-channel battery-cell controller IC. The chip adds a separate ADC to each input channel to deliver faster, more accurate insights into high-voltage batteries. Typically, a BMS includes a cell monitoring unit (CMU) to measure voltages and, occasionally, currents at the cell level; a battery disconnect unit (BDU) to monitor voltages, currents, and temperatures at the pack level; and a gateway to communicate with the main MCU. NXP said the new chip can handle functions from each of these systems, cutting external component count by up to 50%.
Finally, Electronic Design is taking part in a three-day virtual event all about the transformation of the data center, including several areas of interest to the analog and power crowd. Senior Content Director Bill Wong is conducting several panel sessions, including one titled, "Powering Boards in the Data Center," which starts July 23 at 3 PM ET.
