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.
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 ...

The electromagnetic rail aircraft launch system: Objectives and …
WEBJun 11, 2019 · Now, a long-awaited replacement which is based on a radically new approach called the Electromagnetic Aircraft Launch System (EMALS) is closer to full tests and eventual deployment, using an electromagnetic “rail gun” to launch/arrest aircraft. The development has been long and troubled, and there is no assurance it will succeed.
What is leakage current? - Electrical Engineering News and Products
WEBJul 24, 2017 · Leakage current can create a constant waste of energy, and in consumer end-user circles is called “vampire power” loss; the answer to which is to unplug chargers when not in use. Power loss is not the only problem that leakage current can create, however. Current can leak from one circuit to another if …
An Inside Look At The Automotive Ethernet Protocol
WEBAug 6, 2018 · Automotive Ethernet provides higher bandwidth data transmissions compared with LIN (19.2 kb/s), CAN FD (15 Mb/s), FlexRay (10 Mb/s), and MOST (25, 50, or 150 Mb/s shared). The LIN protocol really only sees usage for very low-bandwidth applications controlling body electronics such as windows or lights. CAN and/or CAN FD offers a …
Practical electromagnet design - Electrical Engineering News and …
WEBDec 26, 2016 · We then calculate the MMF density (H) by dividing the MMF by the length of the electromagnet core in meters. So if your electromagnet is 0.02m (2cm) long, H would be 10AT/0.02M =500AT per meter. But H will not be used in the practical formula that described below. Instead, the AT and electromagnet length will be …
