    Accelerate your electric mask design

    Wearing an electric mask, also known as an E-mask or digital mask, can increase your comfort level compared to disposable or N95 masks. An electric mask is similar to a central ventilation system: a fan inside the mask allows users to inhale the outside air, which enters the mask after being filtered through a filter element. This design helps combat...

    3 big benefits of small cells

    We’ve all experienced the inconvenience of a dead spot. Macro remote radio units (RRUs), also known as macro cells, are typically deployed in a centralized location to cover dense urban areas. As the number of people using RRUs grows beyond capacity, the system’s signal overloads and weakens. To increase the capacity of the network in high...

    How to use Hall-effect current sensors in telecom rectifiers and server PSUs

    Power-factor correction (PFC) and inverters in telecom rectifiers and server power-supply units (PSUs) need to be able to sense the current signal from the high-voltage side for the controller at the low-voltage side. To do so, they use an isolated current sensor. There are many choices for isolated current sensing like current transformers (CTs), isolated...
