Texas Instruments (TI) has debuted the industry’s first stand-alone active electromagnetic interference (EMI) filter integrated circuits (ICs), enabling engineers to implement smaller, lighter EMI filters, to enhance system functionality at reduced system cost — while simultaneously meeting EMI regulatory standards. As electrical systems become increasingly dense and interconnected, mitigating EMI is a critical system design…
Transfer function, quality factor, and cut-off frequency
To better understand a filter’s functionality and performance, there are mathematical functions that represent a filter theoretically, such as transfer function, quality factor, and cutoff frequency. Understanding these terms will make it easier to understand a filter property. Terminologies (definitions) Transfer function: The inputs and outputs of an op-amp circuit may be voltages, currents, or…
STMicroelectronics’ common-mode filters ensure signal integrity in serial interfaces
New common-mode filters from STMicroelectronics have an extremely wide differential bandwidth of 10.7GHz to protect antenna sensitivity in adjacent wireless circuitry from the latest serial digital interfaces. The 2-channel ECMF2-40A100N10 and 4-channel ECMF4-40A100N10 are compatible with high-speed interface standards including USB 3.2 Gen 2, USB4, HDMI 2.1, and DisplayPort. With their low serial resistance of just 3Ω,…
