Proper control loop phase and gain measurements should be made by factory experts possessing (expensive) equipment and commensurate experience. For those who do not have access to one or either of these, there is an alternative.

One potential source of emissions is the switching node, referred to as SW on many schematics. The SW node copper can act as an antenna, transmitting the noise generated by fast and efficient high power switching events. This is the main source of emissions for most switching regulators.

Automotive application circuits must meet strict EMI standards to avoid interfering with broadcast and mobile service frequency bands. In this article we look specifically at two possible solutions for a 4-switch buck-boost controller and compare EMI chamber results.

EMI from switching regulators is broken down into radiated and conducted emissions (CE). This article focuses on conducted emissions, which can be further classified into two categories: common-mode (CM) noise and differential-mode (DM) noise. Why the CM-DM distinction?

Precision data acquisition (DAQ) systems are popular in industrial applications. In some DAQ applications, low power and ultralow noise are required. One example is seismic sensor-related applications, where a lot of information can be extracted from seismic data that is useful for a wide range of applications such as structural health monitoring, geophysical research, oil exploration, and even industrial and household safety (Reference 1.)

Analog Devices announced that its expanded portfolio of battery management system (BMS) products including ASIL-D functional safety and new low-power features to enable continuous battery monitoring.

Analog Devices and Audinate have introduced the Dante Embedded Platform (DEP) SDK for ADI's SHARC audio DSPs, which layers audio-over-IP network software on multicore SHARC ADSP-SC5xx applications processors. The single-chip solution has been validated by Audinate, allowing engineers to develop with confidence using the DEP for SHARC solution.
