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 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] ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...
