Analog-filter designs manage an uncommonly large number of core parameters compared with designs of other analog-circuit-block types. First, the application usually suggests the overall spectral shape ...

Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...

This file type includes high resolution graphics and schematics. All high-speed analog-to-digital converter (ADC) datasheets show specified performance that really should be considered an ideal ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...

Precision signal chain designers are challenged to meet noise performance demands in medium bandwidth applications and often end up making a trade-off between noise performance and accuracy. Achieving ...
