A filter is a device that passes or rejects certain frequencies of a signal. Three common type of filters are the low- pass filter the bandpass filter, and the high-pass filter. An ideal low-pass ...

The switched-capacitor (SC) techniques enable the design of various filters that can be realized in monolithic integrated circuits from using state-of-art MOS technology. By replacing the noisy ...

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 ...

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 ...

In the 1960s, mainframe computers took up entire rooms. By the 1980s, there were individual workstations and just a few decades later, laptops and smartphones became ubiquitous. Today’s technology is ...

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 ...

A research team led by Prof. MENG Guowen and Prof. HAN Fangming from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), along with Prof. WEI Bingqing from the ...

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 ...
