This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace. It is shown that a PCB trace can be modeled as a resonant RLC network just like the standard components and effectively constitutes the fourth circuit component whose frequency behavior directly affects the impedance of the resistors, inductors, and capacitors on a PCB.

Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, an SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators.

Analog Devices and Würth Elektronik Webinar

A reference design almost never fits completely. We will discuss some of the commonly encountered pitfalls when adapting reference designs to your own needs.

For example max current vs current limit, Switching frequency vs. efficiency and/or Noise, input/output voltage range, and so on. Here as well we will...

Capacitors are used in both analog and digital circuits to remove unwanted signals. The filtering performance of a capacitor or filtering circuit is commonly described in terms of insertion loss. Some of the factors that significantly affect the insertion loss performance of a filtering circuit include configuration of the filtering elements, impedance, and load current.
