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 ...

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 ...

EMC requirements are driving up the cost of low-priced, but noisy brush DC motors. Monolithic EMI filters reverse this trend. Brush DC motors are inexpensive and easy to operate, providing a good ...
