In today's world of increasing electrical noise, higher-speed logic, and more-sensitive circuits, the need for high-frequency noise filtering is especially critical. Noise can enter a circuit through ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

As switch mode power supplies continue to increase the frequency at which they operate, the filter capacitor becomes more important. This guide gives some great insight into the selection and mounting ...

The impact of switched capacitor filters on integrated filter design in the late 1970s was truly revolutionary, and is still considered one of the most significant inventions in the history of ICs [1] ...

For EMI filtering and noise attenuation, California-based Johanson Dielectrics is offering a range of novel multi-layer ceramic devices that combines two balanced shunt capacitors with mutual ...

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...
