Optimizing Power Systems for the Signal Chain—Part 1: How Much
Power Supply Noise Is Tolerable?
This article gives an overview of how to quantify the power supply noise sensitivity of the loads in
the signal processing chain, and how to calculate the maximum acceptable power supply noise.
Measurement setups are also discussed along with some strategies on how to meet power domain
sensitivity with realistic power supply noise requirements. The next articles in this series will take a
deeper dive into optimizing power distribution networks for ADCs, DACs, and RF transceivers.

Rarely Asked Questions—Issue 187: How to Choose the Right
Protection for Your Circuit
With an increase in the amount of electronics used in different applications as well as the fusion
of functions controlled by expensive FPGAs or microcontrollers, it is ever more important to protect
these devices from the harsh environments in which they operate. Because of the wide range
of devices available, the most difficult problem for the designer is simply choosing appropriate
solutions. We’ll discuss application challenges and why protection is needed, as well as compare
traditional methodologies with newer, alternative solutions that offer better accuracy, reliability, and
design flexibility.
