The basics: What is EMC? - Electrical Engineering News and Products
WEBJan 12, 2022 — EMC stands for Electromagnetic compatibility, which means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment. It does not emit levels of EM energy that generate electromagnetic interference (EMI) in other devices in the vicinity. Electromagnetic interference (EMI) is the interference ...
MIM/MOM capacitor extraction boosts analog and RF designs
WEBApr 29, 2020 — MIM/MOM capacitors. Metal-insulator-metal (MIM) and metal-oxide-metal (MOM) capacitors are widely used in analog/RF designs because of their desirable characteristics: High-capacity density due to minimum width and spacing of metals. Good matching characteristics due to lateral coupling. Symmetric plate design.
Semiconductor manufacturing: past, present, and future
WEBJan 26, 2022 — New technology, like selective deposition-enabling technology, will allow semiconductor manufacturers to be even more precise about what they deposit on a wafer. To accommodate that, fluid systems will have to become even more precise as well. In addition, the age of silicon wafers may soon be coming to an end.
Flyback power converters, Part 1: basic principles
WEBApr 15, 2019 — A: A flyback converter is a simple implementation of a switch-mode power supply (SMPS), and it can be designed to deliver a DC output from either an AC or DC input, with outputs both lower and higher than the supply source (buck/boost operation). It has two distinct operating phases, with a basic principle that power from the input side is ...
